Write a C++ program according to given function prototype Given an array A, make a triangle such that the bottom most level has all array elements. Then, at each level number of elements is one more than the previous level. Elements at each level is the sum of consecutive elements in the previous level. Function prototype to use : int** sum_of_sequence(int arr,int size) Example : Input: [1.2,3,4,5]

Output: [3,5,7,9]

[8,12,16]

[20,28]

[48]
