Given an array of random numbers, Write a c code to move all zeros to end of an array. An array contains only positive number. For example - Input int arr[] = {1,6,0,3,8,9,0,2}; Output  // Move all zero at the end int arr[] = {1,6,3,8,9,2,0,0};   How to Move all Zeros to End of an Array Traverse an array and push all non-zero element in an array. Maintain the count.

Write a C, C++ code to implement binary search program using recursion.  What is Binary Search?  Binary Search algorithm is used to search an element in a sorted array. Binary search works by comparing the value to the middle element of an array. If the value is found then index is returned otherwise the steps is repeated until the value is found. It is faster than linear search.
