Example:
string1 = 'qwe'
string2 = 'asd'
string_map(string1, string2) == True
#q = a, w = s, and e = d
Note: This example would return False if the letters were repeated; for example, string1 = ‘donut’ and string2 =’fatty’. This is because the letter t from fatty attempts to map to two different outcomes (t = n or t = u)..
