Write a function, named replace, that has three parameters: (1) a string named original, (2) a single-character string, named old, representing the character to be replaced, (3) another single-character string, named new, representing the character to be used for replacement. The function should return a new string where every occurrence of old in the passed-in string is replaced by new. You should write a loop to implement such a functionality.
