Given an array gpa of student GPA scores, where each GPA is a floating-point number in the range 0.0 to 4.0 inclusive with at most two decimal places, return the GPA scores sorted in ascending order using the Bucket Sort algorithm.

Return the values as numbers, preserving trailing decimal zeros is not required.

Example 1:

Input: gpa = [1.2, 0.8, 2.0, 1.5, 0.9, 1.2]
Output: [0.8, 0.9, 1.2, 1.2, 1.5, 2.0]
Explanation: The GPA scores are arranged from smallest to largest. The duplicate value 1.2 appears twice in the sorted result.

Example 2:

Input: gpa = [3.75, 2.5, 4.0, 3.2, 2.75, 3.0]
Output: [2.5, 2.75, 3.0, 3.2, 3.75, 4.0]
Explanation: All GPA scores are sorted in ascending order, including the maximum possible GPA of 4.0.

Example 3:

Input: gpa = [4.0, 0.0, 2.5, 4.0, 0.0, 3.5]
Output: [0.0, 0.0, 2.5, 3.5, 4.0, 4.0]
Explanation: The minimum GPA 0.0 and maximum GPA 4.0 are both valid values and are placed correctly in sorted order.

Constraints

1 <= gpa.length <= 100

0.0 <= gpa[i] <= 4.0
