Write a function that takes in an array of integers and returns the integers that are either palindromes or almost-palindromes. An almost-palindrome is any integer that can be rearranged to form a palindrome. For example, the numbers 677 and 338 are both almost- palindromes, since they can be rearranged to form 767 and 383, respectively. Examples palindromeSieve([443, 12, 639, 121, 3232]) // Since 443 => 434; 121 is a palindrome; 3232 => 2332 or 3: [443, 121, 323

Given a square matrix, calculate the absolute difference between the sums of its diagonals. For example, the square matrix is shown below: 1 2 3 4 5 6 9 8 9 The left-to-right diagonal = . The right to left diagonal = . Their absolute difference is . Function description Complete the function in the editor below. diagonalDifference takes the following parameter: int arr[n][m]: an array of integers Return int: the absolute diagonal difference Input Format The first line contains a single integer, , the number of rows and columns in the square matrix .Each of the next lines describes a row, , and consists of space-separated integers . Constraints Output Format Return the absolute difference between the sums of the matrix's two diagonals as a single integer. Sample Input 3 11 2 4 4 5 6 10 8 -12 Sample Output 15 Explanation The primary diagonal is: 11 5 -12 Sum across the primary diagonal: 11 + 5 - 12 = 4 The secondary diagonal is: 4 5…
Write a function is ordered that takes an integer array and its size as parameters and returns true if the array elements are ordered in nondecreasing order and returns false if not. For example, integers in {10,0,1,1,5,1009} are ordered in nondecreasing order. On the other hand, integers in {1, 2, 3, 8, 4, 19} are not since 8 > 4
There is a large pile of socks that must be paired by color. Given an array of integers representing the color of each sock, determine how many pairs of socks with matching colors there are. Example There is one pair of color and one of color . There are three odd socks left, one of each color. The number of pairs is . Function Description Complete the sockMerchant function in the editor below. sockMerchant has the following parameter(s): int n: the number of socks in the pile int ar[n]: the colors of each sock Returns int: the number of pairs Input Format The first line contains an integer , the number of socks represented in .The second line contains space-separated integers, , the colors of the socks in the pile.

Write a program that uses a 3 x 3 array and randomly place 0 or 1 into the nine squares to play the tic-tac-toe game. The program detects a win when the sum of any row, any column, or any diagonal is equal to either 0 or 3. Your program must contain at least the following functions: a function to randomly fill the array with 0's or 1's and a function to determine if a win is detected in the array. Run these functions for some large number of times, say 1,000, 10,000, or 1,000,000, and see the number of times a win is detected. Consider the provided function main in main.cpp: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . . }
Write a function that determines standartdeviation of float array. The function takes dataset as afloat array parameter!! And it also return result as afloat.(Clue: calculate average first) Definations: in the image σ = standard deviationxi = each value of dataset? (with a bar over it) = the arithmetic mean of the data(This symbol will be indicated as average of dataset)N = the total number of data points(if you need square root of some number you can use sqrtfunction in math.h library. Usage example: a=sqrt(b);which means “a” is equal to square root of “b”)
An array with an odd number of elements is said to be centered if all elements (except the middle one) are strictly greater than the value of the middle element. Note that only arrays with an odd number of elements have a middle element. Write a function that accepts an integer array and returns 1 or “Centred” if it is a centered array, otherwise it returns 0 or “Not Centered”.
Write a program thatinputs five integers in twoarrays each. It declares a function thatacceptsfour parameters. The first parameter is the first array, the second parameteris the second array, the third parameter is the third arrayand the The fourth parameteris the length of the arrays. The function adds the corresponding values of thefirst two arrays and stores the result in the Figure-Athe corresponding element of the third array. The main function finally displays the values of all arrays.(Length of all arrays must be same)
