Directions :
Write Java code that prompts the user for a string and tells them if the grouping characters in that string are balanced. Grouping characters are ( and ), [ and ], and { and }.
I got the basic idea for this problem from HackerRank. It's also a very common interview question.
Examples
Enter the expression:{[()]} {[()]}
is balanced
Enter the expression: {()()} {()()}
is balanced
Enter the expression: {([[])} {([[])}
is not balanced
Enter the expression: {([)]} {([)]}
is not balanced
