2. An array A contains n-1 unique integers in the range 0, n-1. So, there is one number in this range that is not in A. Design an O(n)-time algorithm for finding that number. You are only allowed to use O(4) additional space besides the array A itself. Please write your idea first. Then, present your algorithm in pseudo-code and analyze it in time and space.

Implement a Binary Search algorithm, and using the results from Exercise 5, show how longthe Binary Search takes (on average) for arrays of size 10, 100, and 1000. (You do not haveto print out the values in the array).
Write aprogram that, given an array of N distinct int values in ascending order, determineswhether a given integer is in the array. You may use only additions and subtractionsand a constant amount of extra memory. The running time of your program should beproportional to log N in the worst case.
Write a program that reads an array A of N elements containing only 0's and 1's. Your program should find the position of a 0 and replace it with a 1 to get the longest continuous sequence of 1's. Let this position of 0 be called P. Print P if such a 0 exists and print -1 if the original array A contains only 1's. Assume the array indexing starts from 0.
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…
You want to design an algorithm, called minMax(A,p,r), that takes an array of integers and indexes of the first and last elements, and returns the minimum and maximum values in that range. Now write the pseudo code of a divide and conquer (and therefore, recursive) algorithm with the same time complexity (Θ(n)). You can assume that p ≤ r. Also, in your code, you can return two numbers by returning a pair, e.g. “return (a, b)”, and can save the output in a similar way, e.g. “(a, b) = minMax(parameters)”. (Short answer please)

Please Help me with this Problem Given an unsorted array of size n. Array elements are in the range from 1 to n. One number from set {1, 2,..., n} is missing and one number occurs twice in the array. Find these two numbers.
You're given an array arr. Apply the following algorithm to it: find intervals of consecutive prime numbers and consecutive non-prime numbers; replace each such interval with the sum of numbers in it; if the resulting array is different from the initial one, return to step 1, otherwise return the result. Input A non-empty integer array such that: -10000 ≤ arr[i] ≤ 10000 1 ≤ arr.length ≤ 1000 Output An integer array. Examples For arr = [1, 2, 3, 5, 6, 4, 2, 3] the result should be [21, 5]: [1, 2, 3, 5, 6, 4, 2, 3] --> [(1), (2 + 3 + 5), (6 + 4), (2 + 3)] --> [1, 10, 10, 5] [1, 10, 10, 5] --> [(1 + 10 + 10), (5)] --> [21, 5] For arr = [-3, 4, 5, 2, 0, -10] the result should be [1, 7, -10]: [-3, 4, 5, 2, 0, -10] --> [(-3 + 4), (5 + 2), (0 + -10)] --> [1, 7, -10] Solve it in C# please
Let A be an array of numbers. In the maximum sub-array problem, your goal is to determine the sub-array A[x . . . y] of consecutive terms for which the sum of the entries is as large as possible. For example, if A = [−2, −3, 4, −1, −2, 1, 5, −3], the maximum sub-array is [4, −1, 2, 1, 5], and the largest possible sum is S = 4 − 1 − 2 + 1 + 5 = 7. Suppose A = [1, 2, −4, 8, 16, −32, 64, 128, −256, 512, 1024, −2048]. Determine S, the largest possible sum of a sub-array of A.
