    while(sum(arr)!=4):
    if arr[i]==1:
    return(‘NO ‘+str(sum(arr)))

    If all N robots have a cake, output “Yes” (without quotes).
    Otherwise, output “No” (without quotes) followed by a space and the number of robots which have a cake.

    Input
    The first line of input contains a single integer T denoting the number of test cases.
    The single line of each test cases contains two space separated integers N and M.

    Example
    Input:
    3
    2 0
    2 1
    4 2

    Output:
    No 1
    Yes
    No 2
