can you solve this please ? Given an array of unsorted integers, you are requested to investigate whether there exist a pair of numbers in this array that has a sum equal to a given key or not. For example, if the arr = [8, 7, 2, 5, 3] and the key = 12, the answer will be "Yes" as the array has a pair (7 and 5) where their sum = 12 = key, otherwise "No" is returned. To solve this problem, the following idea can be used: i. Consider every pair in the given array and check if their sum = key. ii. Sort the array first, keeping two pointers to on the minimum and maximum of the array and then move from both directions toward the center of the array while checking whether the sum = key or not. Answer the following questions: a) Transform each of the above ideas (i) & (ii) into algorithm (pseudocode) and compute their complexities b) Critic these two ideas: [Which is better? Why?] c) Design a better solution with less complexity. [note: your idea should be…
Given a sorted array of n integers that has been rotated an unknownnumber of times, write code to find an element in the array. You may assume that the array wasoriginally sorted in increasing order.EXAMPLElnput:find5in{15, 16, 19, 20, 25, 1, 3, 4, 5, 7, 10, 14}Output: 8 (the index of 5 in the array Given a sorted array of n integers that has been rotated an unknownnumber of times, write code to find an element in the array.

Suppose that you are playing a card game whose goal is to collect exactly k cards with a total value of t. Write a solution that can determine if it is possible for a given collection of cards whose values are given in the array values. For example, if the array contained the values <10,5,7,2>, k = 3, and t = 12, you would return false because no three values add to 12. However, if t = 14, you would return true, since 5 + 7 + 2 = 14. So I considered this to be a form of groupSum recursion, so I try to implement it in recursion form. However, since the passing parameters are not the incrementing level index but 'k' that is the limit number of the numbers we can choose from the array, I cannot use passing index through recursion to search from the start of the array toward the end of the values.length(the length of the array). would there be any method I can use to increment and search along the array using k, the number of numbers we can add into the total(t) instead of the…
Please code in python.Given an array of integers a of even length, your task is to split it into two arrays of equal length such that all the numbers are unique in each of them. There may be more than one possible answer, in which case you may return any of them. If there are no possible answers, return an empty array. Hint: Count the number of occurrences of each integer in a. If there are integers occurring more than twice, then there is no solution. Next, put the integers occurring twice into both answer arrays. Finally, put all other numbers in the answer arrays, following the condition that they should have equal sizes. Example • For a = [2, 1, 2, 3, 3, 4], the output can be solution(a) = [[2, 1, 3], [2, 3, 4]]. Answers like [[1, 2, 3], [2, 3, 4]] or [[4, 2, 3], [3, 2, 1]] would also be considered correct. • For a = [1, 2, 2, 1], the output can be solution(a) = [[1, 2], [2, 1]]. Again, there are other possible answers. • For a = [2, 2, 3, 3, 2, 2], the output should be solution(a)…
3. Write a program to find intersection of two sorted array.For example, if the two sorted arrays as input are {21, 34, 41, 22, 35} and {61, 34, 45, 21, 11}, it should returnan intersection array with numbers {34, 21}. For the sake of this Problem, you can assume that numbers ineach integer array are unique.
You are a professional robber planning to rob houses along a street. Each house has a certain amount of money stashed. All houses at this place are arranged in a circle. That means the first house is the neighbor of the last one. Meanwhile, adjacent houses have a security system connected, and it will automatically contact the police if two adjacent houses were broken into on the same night. Given an integer array nums representing the amount of money of each house, return the maximum amount of money you can rob tonight without alerting the police. Example 1: Input: nums = [2,3,2] Output: 3 Explanation: You cannot rob house 1 (money = 2) and then rob house 3 (money = 2), because they are adjacent houses.
You have an array of four integers that has been sorted from lowest to greatest value in the array. You also have a function that does a bubble sort in order to arrange things from lowest to greatest priority. If you call this method on your array, the function will perform at least one swap on your array. If false, why is it untrue?
You can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e., all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array and the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed) Main method firstly constructs a 2D array of certain sizes and then construct a TwoD object and drive the task according to the above runtime interactions and displays. TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some “deep” copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e.,…
You have been given an array A of size N and an integer K. This array consists of N integers ranging from 1 to 10^7. Each element in this array is said to have a Special Weight. The special weight of an element a[i] is a[i]%K. You now need to sort this array in Non-Increasing order of the weight of each element, i.e the element with the highest weight should appear first, then the element with the second highest weight and so on. In case two elements have the same weight, the one with the lower value should appear in the output first. Input Format: The first line consists of two space separated integers N and K. The next line consists of N space separated integers denoting the elements of array A. Output Format: Print N space separated integers denoting the elements of the array in the order in which they are required. Constraints: 1≤N≤10^5 1≤A[i]≤10^7 1≤K≤10^7 Note: You need to print the value of each element and not their weight. SAMPLE INPUT 5 21 2 3 4 5 SAMPLE OUTPUT 1 3 5 2 4…
Suppoce we're given numpy arrays of names and scores, where each row in the scores array lists the midterm and final scores for that respective student. For example, Carol has a 75 on the midterm and 99 on the final. names = np. array([ "Alice" "Bob". "Carol","Derek ","Erin"]) Scores = np.array([ [95, 98], [82, 88], [75, 99], [80, 90], 85, 82 ]]) Write function avgMidtermNoC that takes ve parameters names and score arrays, and returns the average score on the midterm, exduding anyone who's name starta with C.
Can you help me please: have the program know when numbers out of the array boundaries are received and mitigate those problems. The given code intentionally induces numbers out of bounds and the student’s portion must correct for this. As always use a header file and implementation file to do those calculations. Remember not to change the given code below in any way Design and implement the class myArray that solves the array index out of bounds problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:myArray list(5);                                  //Line 1 myArraymyList(2, 13);                     //Line 2myArray yourList(-5, 9);                    //Line 3The statement in Line 1 declares list to be an…
A) You have been given two random integer arrays as arr1 and arr2 of size n and m respectively. Boththe arrays contain numbers from 0 to 9 (i.e. single digit integer is present at every index). The ideahere is to represent each array as an integer in itself of digits n and m.You need to find the sum of both the input arrays treating them as two integers and put the result inanother array i.e. output array will also contain only single digit at every index.Input Format:Line 1: Size of first arrayLine 2: Elements of first arrayLine 3: Size of second arrayLine 4: Elements of second arrayOutput Format:The resultant arraySample Input 1:36 2 437 5 6Sample Output 1:1 3 8 0Sample Input 2:49 7 6 134 5 9Sample Output 2:1 0 2 2 0 PLEASE WRITE A PROGRAM IN JAVA.
