Problem 43607. Logical array indexing - part 1

Given an array A of size p x q , return an array Y of the same size such that the following conditions are satisfied.

(1) The non-zero elements should be greater than a given value 'n' .

(2) These non-zero entries in Y should have the same values as their corresponding elements in A

For example: Given A = [3 4 5 6 2 4 5 6 3 6] and n = 4 , return Y = [0 0 5 6 0 0 5 6 0 6]
