June 2016 - sillyCASE

Task:

Create a function that takes a string and returns that string with the first half lowercased and the last half uppercased.

Example:

foobar => fooBAR

If the string length is an odd number then 'round' it up to find which letters to uppercase. See example below.

sillycase("brian")  
//         --^-- midpoint  
//         bri    first half (lower-cased)  
//            AN second half (upper-cased)
