Given an array of random numbers, Push all the zero’s of a given array to the end of the array. For example, if the given arrays is {1, 9, 8, 4, 0, 0, 2, 7, 0, 6, 0}, it should be changed to {1, 9, 8, 4, 2, 7, 6, 0, 0, 0, 0}. The order of all other elements should be same. The expected time complexity is O(n) and extra space is O(1).
How react works?
A Function is given an Array of integers (arr) and a Number (k) as arguments. The integers in arr must be added together sequentially, and each sum of the integers must be compared to k. If the sum matches k, then it should be documented that a sum matched k. Once arr has been completely looped through, the total number of correct matches should be returned.
