Sort Positives, Keep Negatives

Write a function that sorts the positive numbers in ascending order, and keeps the negative numbers untouched.

Examples

pos_neg_sort([6, 3, -2, 5, -8, 2, -2]) ➞ [2, 3, -2, 5, -8, 6, -2]

pos_neg_sort([6, 5, 4, -1, 3, 2, -1, 1]) ➞ [1, 2, 3, -1, 4, 5, -1, 6]

pos_neg_sort([-5, -5, -5, -5, 7, -5]) ➞ [-5, -5, -5, -5, 7, -5]

pos_neg_sort([]) ➞ []

Notes

• If given an empty list, you should return an empty list.
• Integers will always be either positive or negative (0 isn't included in the tests).
