Given an array A of non-negative integers of size m. Your task is to sort the array in non-decreasing order and print out the original indices of the new sorted array. e.g.A={4,5,3,7,1} After sorting the new array becomes A={1,3,4,5,7}. The required output should be “4 2 0 1 3” Answer You need to pair (tuple) the value with the original
