Write a function properlybalanced that uses a stack to check if a string contains properly balanced delimiters. this function returns true if a string containing braces, parentheses, and brackets is properly delimited. otherwise, it displays a message stating why the string is not properly balanced (extra closing delimiter, a missing closing delimiter, delimiter mismatch) and returns false.

the major difference between the two is the objective and the reward of the game. candy crush has a puzzle theme with the objective of meeting a specific quota of points or objects, you are able to gain access to the next level and compete with peers on the process. on duolingo the objective is rather different, you are given sets of questions for you to answer for you to move to the next level and as for the reward, you are able to learn available language as this is an app developed to teach the user about other languages.
