Problem Description
The definition of the end number: If a positive integer greater than 1 equals the sum of all the factors of its own, then it is said that the number is the end number, such as 6, 28 is the end number: 6=1+2+3;28=1+2+4+7+14.

The task is to determine the number of two positive integers.

Input
The input data contains multiple lines, the first line is a positive integer n, which indicates the number of test instances, then the N test instances, each one row, consisting of two positive integers num1 and num2, (1
