Problem statement
Given a string str consisting of parenthesis from [ “(” , “)” , “{” , “}” , “” , “” ]. If the String is perfectly
balanced return 0 else return the index(starting from 1)at which the nesting is found to be wrong.
Input Format
A single line of input has string 's' which contains the parenthesis
Constraints
1<=|s|<=100
Output Format
As mentioned in the problem statement.

PYTHON CODE:

string=str(input())

# Storing opening braces in list lst1
lst1 =['{', '(', '[']

# Storing closing braces in list lst2
lst2 =['}', ')', ']']

# Creating an empty list lst
lst =[]

# Creating dictionary to map
# closing braces to opening ones
Dict ={ ')':'(', '}':'{', ']':'['}

a = b = c = 0

# If first position of string contain
# any closing braces return 1
if string[0] in lst2:
    print(1)

else:
    # If characters of string are opening
    # braces then append them in a list
    for i in range(0, len(string)):
        if string[i] in lst1:
            lst.append(string[i])
            k = i + 2
        else:
            # When size of list is 0 and new closing
            # braces is encountered then print its
            # index starting from 1
            if len(lst)== 0 and (string[i] in lst2):
                print(i + 1)
                c = 1
                break
            else:
                # As we encounter closing braces we map
                # them with theircorresponding opening
                # braces using dictionary and check
                # if it is same as last opened braces
                #(last element in list) if yes then we
                # delete that elememt from list
                if Dict[string[i]]== lst[len(lst)-1]:
                    lst.pop()
                else:
                    # Otherwise we return the index
                    # (starting from 1) at which
                    # nesting is found wrong
                    print(i + 1)
                    a = 1
                    break

    # At end if the list is empty it
    # means the string is perfectly nested
    if len(lst)== 0 and c == 0:
        print(0)
        b = 1

    if a == 0 and b == 0 and c == 0:
        print(k)

Problem statement
Given a string and an integer 'n'. Rotate the string left or (anti-clockwise) if 'n' is odd else rotate the
srtring right or (clockwise)
Input Format
First line of input contains string 's'. Next line of input contains integer 'n'
Constraints
1<=n<=|s|<=100
Output Format
The resultant string.

C++ CODE:

#include<bits/stdc++.h>
using namespace std;

// In-place rotates s towards left by d
void leftrotate(string &s, int d)
{
    reverse(s.begin(), s.begin()+d);
    reverse(s.begin()+d, s.end());
    reverse(s.begin(), s.end());
}

// In-place rotates s towards right by d
void rightrotate(string &s, int d)
{
   leftrotate(s, s.length()-d);
}

// Driver code
int main()
{
    string str;
    int n;
    cin>>str>>n;
    if(n%2==0)
        rightrotate(str,n);
    else
        leftrotate(str,n);
    cout<<str;
}
