+
+Your task is to make a function that can take any non-negative integer as an argument and return it with its digits in descending order. Essentially, rearrange the digits to create the highest possible number.
+
+**Examples**:
+Input: `42145` Output: `54421`
+Input: `145263` Output: `654321`
+Input: `123456789` Output: `987654321`
