// Naman and Mohit are playing a mystical Stone Reversal Game. They take turns handing each other a name engraved on a magical stone. The challenge is to reverse the name on the stone up to a specific position and read aloud the new magical word. Write a program to help Naman and Mohit perform this magical transformation.

// Input Format

// Take T test cases as the input.
// First line of input under each test case should be K, the position up to which the magical name has to be reversed.
// Second line of input should be the magical name S engraved on the stone
// Constraints

// 1≤ T≤ 1000
// 1 ≤ S.size() ≤ 1000
// 0≤ K ≤S.size()
// Output Format

// Print the newly reversed magical name for each test case.
