Look at some strings and decide if they are equal. Two strings are equal if they are the same length and have the same characters in the same order.
Is this string: "Xqovrfiwur0 ksduiowojsdsxx yyyx ,.sd+^% xanpo ,,woath wu,bny"
equal to this string: "Xqovrfiwur0 ksduiowojsdsxx yyyx ,.sd+^% xanpo ,,woath wu,bny" ?
Hint: the tails of the two strings are equal.
