Given an n x m matrix, where every row and column is sorted in increasing order, and a number x . The task is to find whether element x is present in the matrix or not.
Expected Time Complexity : O(m + n)
The first line of input contains a single integer T denoting the number of test cases. Then T test cases follow. Each test case consists of three lines.
First line of each test case consist of two space separated integers N and M, denoting the number of element in a row and column respectively.
Second line of each test case consists of N*M space separated integers denoting the elements in the matrix in row major order.
Third line of each test case contains a single integer x, the element to be searched.
Corresponding to each test case, print in a new line, 1 if the element x is present in the matrix, otherwise simply print 0.
