You are given an array A of size N, and you are also given a sum. You need to find if two numbers in A exists that have sum equal to the given sum.
The first line of input contains T denoting the number of testcases. T testcases follow. Each testcase contains three lines of input. The first line contains N denoting the size of the array A. The second line contains N elements of the array. The third line contains element sum.
For each testcase, in a new line, print the required output.
Since this is a function problem, you don't need to take any input. Just complete the provided function sumExists().
1 <= T <= 100
1 <= N <= 1000
1 <= Ai <= 106
