* CODERBYTE BEGINNER CHALLENGE *

* *

* Swap Case *

* Using the JavaScript language, have the function SwapCase(str) take the str *

* parameter and swap the case of each character. For example: if str is "Hello World" *

* the output should be hELLO wORLD. Let numbers and symbols stay the way they are. * *

* *

* SOLUTION *

* I am going to be using a new string to store my modified results. I am going to *

* loop thru every character and covert it to UpperCase. Then I am going to compare *

* that to the character in the string. If they are the same - meaning both are *

* uppercase then I am going to return the lowercase of the character. If they are not *

* the same then return the Uppercase character.

* *

* Steps for solution *

* 1) Create new string to hold my results *

* 2) Loop thru each character in the string *

* 3) Save the uppercase of this character in u *

* 4) Compare uppercase to current character *

* 5) If they are the same then return the lowercase *

* 6) Else return uppercase *

* *
