3Suppose we used an int array arr of size N+1 to keep track of the frequency with which we have seen a given number in the interval [0 … N]. That is, arr[i] = x if we have seen number i a total of x times so far. What limitation of arrays should we still be concerned about in this specific context?
1. AWe cannot easily insert an element in front of others.
2. BChecking whether an array contains a number can be time consuming
