Assume double[][] x = new double[2][5], what are x.length, and x[1].length?
in c++ You are given an array A of non-negative integers of size m. Your task is to sort the array in increasing order and print out the original indices of the new sorted array. Example: A= {12, 2, 6, 10, 9, 24,23, 33} After sorting the new array becomes A= {2,6,9,10,12,23,24,33}. The required output should be sorted array and original indexes "1 2 4 3 0 6 7", index of 2 in original array was 1 , index for 6 was 2 and so on.

In python, Problem Description:Sheldon and Leonard are physicists who are fixated on the BIG BANG theory. In order to exchange secret insights they have devised a code that encodes UPPERCASE words by shifting their letters forward. Shifting a letter by S positions means to go forward S letters in the alphabet. For example, shifting B by S = 3 positions gives E. However, sometimes this makes us go past Z, the last letter of the alphabet. Whenever this happens we wrap around, treating A as the letter that follows Z. For example, shifting Z by S = 2 positions gives B. Sheldon and Leonard’s code depends on a parameter K and also varies depending on the position of each letter in the word. For the letter at position P, they use the shift value of S = 3P + K. For example, here is how ZOOM is encoded when K = 3. The first letter Z has a shift valueof S = 3 × 1 + 3 = 6; it wraps around and becomes the letter F. The second letter, O, hasS = 3 × 2 + 3 = 9 and becomes X. The last two letters…
1. A set of integers are relatively prime to each other if there is no integer greater than 1 that divides all the elements. Furthermore, in Number Theory, it is known that the Euler function,ϕ (n), expresses the number of positive integers less than n that are relatively prime with n. Choose the alternative that has the correct value of ϕ(n) for every n below. A) ϕ(5) = 4 B) ϕ(6) = 2 C) ϕ(10) = 3 D) ϕ(14) = 6 E) ϕ(17) = 16
You are given N sets of integers A1,A2,…,AN. For each valid i, let's denote the elements of the set Ai by {ci,1,ci,2,…,ci,|Ai|}. Find the number of ways to choose a sequence (a1,a2,…,aN) such that: ai∈Ai for each valid I ai≠ai+1 for each valid i and a1≠aN. Since this number may be large, compute it modulo 998,244,353.

python this is connected to the last problem - the second part of the question is added. my attempt on this problem shows that the part b) (approaches N*NH) is not really wokring.. a) (answered) with a function “harmonic(n)” that computes the n-th harmonic number, write a function “harmonic_all(n)” that returns the number of values generated until all values are obtained as a function of the range of possible values n, then write a function “harmonic_sim(n)” that repeats “harmonic_all(n)” a total of n_sim = 100 times. (Attaching the code from the answer for a) d) Show that as n increases (e.g., with a doubling experiment), from n = 2 to n_max = 1,000, the value of “coupon_sim(n)” approaches “n * Hn”.
Write a fraction calculator program that adds, subtracts, multiplies, and di-vides fractions. Your program should check for the division by 0, have and use the following functions:(a) subtract - finds the reduced difference of a pair of given fractions, by makingthe second fraction negative then using the add function.(b) multiply - finds the reduced product of a pair of given fractions.(c) divide - finds the reduced quotient of a pair of given fractions by inverting the second fraction then using the multiply function

This exercise asks you to write * a program that, given a sequence * * s(0), s(1), ..., s(n-1) * * of integers as input, finds a ___longest increasing subsequence___ * of the sequence s. * * For example, suppose we are given as input the sequence * * 72, 16, 51, 17, 6, 21, 92, 59, 54, 78, 41, 33, 94, * 85, 83, 56, 2, 46, 57, 44, 73, 6, 47, 47, 0. * * In this sequence, a longest increasing subsequence has length 7. * One example of such an increasing subsequence is * * 16 < 17 < 21 < 54 < 56 < 57 < 73. * * More generally, your program must be such that * given a sequence * * s(0), s(1), ..., s(n-1) * * of integers as input, the program returns a subsequence * * s(i_1), s(i_2), ..., s(i_k) * * that meets all…
USE PYTHON A left rotation operation on an array of size n shifts each of the array's elements 1 unit to the left. For example, if 2 left rotations are performed on array [1,2,3,4,5] , then the array would become [3,4,5,1,2] When we perform 4 left rotations, the array undergoes the following sequence of changes: Write code for a procedure that given an array of n integers and a number, d, performs d left rotations on the array. Then return resulted array.
please code in pythonwe have to perform nested function To illustrate this with an example: - -The input number is 20 as in: `wraps_diff_sum_digits(20)` - `wraps_diff_sum_digits` calls `diff_sum_digits(20)` which calls `sum_digits(20)` - `sum_digits` adds the numbers (2+0 = 2) returns a 2, `diff_sum_digits` subtracts (20-2 = 18) and returns this to `wraps_diff_sum_digits` - `wraps_diff_sum_digits` sees that the number 18 stills has 2 digits and calls `diff_sum_digits(18)` which calls `sum_digits(18)` - `sum_digits` add the numbers (1+8 = 9) returns a 9, `diff_sum_digits` subtracts (18-9 = 9) and returns this to `wraps_diff_sum_digits` - `wraps_diff_sum_digits` sees that the number 9 only has 1 digit - stops and returns the value 9.
Part 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column. Below is an example of adding two binary numbers that shows all…
