Write and run a SPIM program (in QtSpim) which takes a string as input, and outputs the same string with the first occurrence of a letter in each word in uppercase, and all other letters in lowercase. Any non-letters should remain as they are. The string can consist of any characters up to a maximum of 100. You may assume that a new word starts after one or more spaces. For example the string "hhdThY 67trrEErr UUUdd$5W" should become "Hhdthy 67Trreerr Uuudd$5w"
