Arrange Students by Height

You are given data from t classes where each class contains a list of students' heights. For each class, the first integer is n — the number of students in that class, followed by n integers representing the heights of the students. Your task is to sort the heights in non-decreasing order for each class.

For instance, if a class has heights [160, 150, 170], the sorted order would be [150, 160, 170].

Input/Output: The program should read from standard input and output the sorted heights for each class on a separate line, with numbers separated by a space.

Note: All formulas or mathematical expressions are represented in LaTeX format. For example, if a formula is needed, it should be written as \( a \leq b \).

inputFormat

The first line contains a single integer \( t \) denoting the number of classes. The following \( t \) lines each start with an integer \( n \) (the number of students in that class) followed by \( n \) integers representing the heights of the students.

Example:

1
3 160 150 170

outputFormat

For each class, output a single line with the sorted student heights separated by a single space.

Example:

150 160 170

## sample

1
3 160 150 170

150 160 170
