Highest and Lowest.md

In this little assignment you are given a string of space separated numbers, and have to return the highest and lowest number.

Example:

highAndLow("1 2 3 4 5"); // return "5 1"
highAndLow("1 2 -3 4 5"); // return "5 -3"
highAndLow("1 9 3 4 -5"); // return "9 -5"

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.
