the hasBalancedParentheses () method. Note: this can be done both iteratively or recursively,
but I believe most people will find the iterative version much easier.
C++: We consider the empty string to have balanced parentheses, as there is no imbalance. Your
program should accept as input a single string containing only the characters ) and (, and output a
single line stating true or false. The functionality for reading and printing answers is written in the
file parentheses.checker.cpp; your task is to complete the has balanced.parentheses ()
function.
**Hint: There's a pattern for how to determine if parentheses are balanced. Try to see if you can find
that pattern first before coding this method up.
Transcribed Image Text:Suppose you are given a string containing only the characters ( and ). In this problem,
you will write a function to determine whether the string has balanced parentheses. Your algorithm
should use no more than O(1) space beyond the input; any algorithms that use space not in O(1) will
receive half credit at most. Any solutions that always return true (or always return false) or otherwise
try to game the distribution of test cases will receive zero credit.
Balanced parentheses means that every open parenthesis has exactly one close parenthesis cor-
responding to it and vice versa, and that for each pair the opening parenthesis precedes the closed
parenthesis. The following strings have balanced parentheses:
()
(() () )
(C() ) ) )
The following strings do not have balanced parentheses:
) (
(()
() ) ())) ))
Java: We consider the empty string to have balanced parentheses, as there is no imbalance. The input
to hasBalancedParantheses will always be a string only containing " (" or ")". Your task is to complete
