Using Stack ADT, write a program to test if a given input string containing the exactly one character $ is in the following set.

L = { w$w: w is an empty string or a string of characters such that each character belongs to the English alphabet {a, b, c, , x, y, z} and w = reverse(w)}

For example, $, abc$cba, raoli$iloar are in L. usca$caus, rao$li, abc$abc are not in L.

Here are sample runs of your program.

Please input a string containing $:

raoli$iloar

raoli$iloar is in that given set.
