Answer:
Code is completed below
Explanation:
Source Code in Java:
class Parenthesis
{
boolean hasBalancedParentheses(String eq) //method to check and return if a set of parenthesis is balanced or not
{
int count=0; //to store count of current unclosed opening brackets
for(int i=0;i<eq.length();i++)
{
if(eq.charAt(i)=='(')
count++;
else if(eq.charAt(i)==')')
count--;
if(count<0) //if count falls below zero, there were more closing brackets than opening brackets till this point
return false;
}
if(count>0) //if count is still more than zero, there were less closing brackets than opening brackets
return false;
return true; //if program reaches this point, it has passed all the tests
}
public static void main(String args[])
{
//testing the function
Parenthesis ob=new Parenthesis();
System.out.println(ob.hasBalancedParentheses("()(()())((())())"));
System.out.println(ob.hasBalancedParentheses(")((()())(()))())"));
}
}
