Given an array containing only 0s and 1s, find the largest subarray which contain equal no of 0s and 1s.
Expected time complexity is O(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 consist of two lines. The first line of each test case consists of an integer N, where N is the size of array.
The second line of each test case contains N space separated integers denoting array elements.
Corresponding to each test case, in a new line, print the starting and ending indexes of the largest subarray which contain equal no of 0s and 1s.
1 ≤ T ≤ 100
1 ≤ N ≤ 500
A[i] = [0,1]
1 1 0 0 0
