Return the Highest and Lowest Numbers

Create a function that accepts a string of space separated numbers and returns the highest and lowest number (as a string).

Examples

highLow("1 2 3 4 5") ➞ "5 1"

highLow("1 2 -3 4 5") ➞ "5 -3"

highLow("1 9 3 4 -5") ➞ "9 -5"

highLow("13") ➞ "13 13"

Notes

• All numbers are valid Int32, no need to validate them.
• There will always be at least one number in the input string.
• Output string must be two numbers separated by a single space, and highest number is first.
