Problem 44499. Capitilize the first letter of every word in a string

For a given input string, capitalize every letter at the beginning of a word, and transform the rest of the letters to lower-case.

Non-letter characters should remain the same.

You can assume there is only one space between every two words.

Examples:

input:  'this is BETTER than C++'
output: 'This Is Better Than C++'

input:  'hEy, tHis iS vErY wroNg!'
output: 'Hey, This Is Very Wrong!'
