Typo Man Go Changyoung

Changyoung always makes exactly one typo when typing a string. Given the typed string and the position of the wrong character, output the string after removing that one character.

The first line contains the number of test cases T (1 <= T <= 1,000).

Each test case is given on one line as an integer P and a string S. P is the 1-based position of the wrong character, and S is the string Changyoung typed. The length of S is at most 80, S contains only uppercase English letters, and P is at most the length of S.

For each test case, output on one line the string after removing the wrong character.
