Write a program to print the sum of the elements of the array with the given below condition. If the array has 6 and 7 in succeeding orders, ignore 6 and 7 and the numbers between them for the calculation of sum.
Eg1) Array Elements - 10,3,6,1,2,7,9
O/P: 22
[i.e 10+3+9]
Eg2) Array Elements - 7,1,2,3,6
O/P:19
Eg3) Array Elements - 1,6,4,7,9
O/P:10

consider an example :
if an array is: 2 -1 2 4 6 -5
then maximum sum of contiguous array is 13, from index 0 to index 4
constraints: complexity must not be greater than O(n).

Say you are given

int a[ ] = {1,2,3,4};
int b[ ] = {4,3,2,1};
int S = 5;

Now the task is to find all pairs of two number which adds up to S (One number from a and other number from b).
