Example 1: Input: N = 5 A[] = { Assume all elements in the array are less than some constant M, Note: Do this without traversing the complete array. If we know that range is small, we use direct address table where we create an array of size equal to maximum value and use array elements as index. Create a recursive function that accepts an array and size. Note: The elements greater than N in the array can be ignored for counting and please read your task section of the problem carefully to understand how to output the array. 3 occurring 2 times.
