Forward this email to a friend or colleague and challenge them to solve it.

Suppose you have an unsorted array of integers. Can you find the number of subarrays that have a sum exactly to the given number p?

    

Input:

array = [10, 2, -2, -20, 10]

k = -10

Output : 3

#The following subarrays [10, 2, -2, -20], [2, -2, -20, 10], [-20, 10] have a sum exactly equal to -10

Input:

array = [9, 4, 20, 3, 10, 5]

k = 33

Output : 2

#The following subarrays [9, 4, 20], [20, 3, 10] have a sum exactly equal to 33
