Input

2				2
babgbag			moonnekky
bag				monkey

rabbbit			abcbbcc
rabbit			abc

• The first line of the input contains an integer N indicating the number of test cases to follow.
• The first line of each test case contains a string X, composed entirely of lowercase alphabetic characters and having length no greater than 10,000.
• The second line contains another string Z having length no greater than 100 and also composed of only lowercase alphabetic characters.
• Be assured that neither Z nor any prefix or suffix of Z will have more than 10100 distinct occurrences in X as a subsequence.

Output

5				8
3				7

• For each test case, output the number of distinct occurrences of Z in X as a subsequence.
• Output for each input set must be on a separate line.
