Given a long integer, we need to find if the difference between sum of odd digits and sum of even digits is 0 or not. The indexes start from zero (0 index is for leftmost digit).
Examples:
Input: 1212112
Output: Yes
Explanation:
the odd position element is 2+2+1=5
the even position element is 1+1+1+2=5
the difference is 5-5=0 equal to zero.
So print yes.Input: 12345
Output: No
Explanation:
the odd position element is 1+3+5=9
the even position element is 2+4=6
the difference is 9-6=3 not equal to zero.
So print no.
Approach:
One by one traverse digits and find the two sums. If difference between two sums is 0, print yes, else no.
Below is the implementation of the above approach:
C++
// C++ program for above approach #include<bits/stdc++.h> using namespace std; bool isDiff0( int n){ int first = 0; int second = 0; bool flag = true ; while (n > 0){ int digit = n % 10; if (flag) first += digit; else second += digit; flag = !flag; n = n/10; } if (first - second == 0) return true ; return false ; } int main(){ int n = 1243; if (isDiff0(n)) cout<< "Yes" ; else cout<< "No" ; return 0; } // This code is contributed by Kirti Agarwal(kirtiagarwal23121999) |
Java
// Java equivalent of above code public class Main { public static boolean isDiff0( int n) { int first = 0 ; int second = 0 ; boolean flag = true ; while (n > 0 ) { int digit = n % 10 ; if (flag) first += digit; else second += digit; flag = !flag; n = n / 10 ; } if (first - second == 0 ) return true ; return false ; } public static void main(String[] args) { int n = 1243 ; if (isDiff0(n)) System.out.println( "Yes" ); else System.out.println( "No" ); } } |
Python
# Python program for the above approach def isDiff0(n): first = 0 second = 0 flag = True while (n > 0 ): digit = n % 10 if (flag): first + = digit else : second + = digit if (flag): flag = False else : flag = True n = int (n / 10 ) if (first - second = = 0 ): return True return False # driver code n = 1243 if (isDiff0(n)): print ( "Yes" ) else : print ( "No" ) |
C#
// C# Program for the above approach using System; public class BinaryTree{ static bool isDiff0( int n){ int first = 0; int second = 0; bool flag = true ; while (n > 0){ int digit = n % 10; if (flag) first += digit; else second += digit; flag = !flag; n = n/10; } if (first - second == 0) return true ; return false ; } public static void Main(){ int n = 1243; if (isDiff0(n)) Console.Write( "Yes" ); else Console.Write( "No" ); } } |
Javascript
// JavaScript prgraom for the above approach function isDiff0(n){ let first = 0; let second = 0; let flag = true ; while (n > 0){ let digit = n % 10; if (flag) first += digit; else second += digit; flag = !flag; n = parseInt(n/10); } if (first - second == 0) return true ; return false ; } let n = 1243; if (isDiff0(n)) console.log( "Yes" ); else console.log( "No" ); // THIS CODE IS CONTRIBUTED BY YASH AGARWAL(YASHAGAWRAL2852002) |
Yes
Time Complexity: O(log n),
Auxiliary space: O(1)
