Check if a number is jumbled or not
Write a program to check if a given integer is jumbled or not. A number is said to be Jumbled if for every digit, its neighbours digit differs by max 1.
Examples :
Input : 6765 Output : True All neighbour digits differ by atmost 1. Input : 1223 Output : True Input : 1235 Output : False
To find if a number is jumbled, we just need to check if a digit has a neighbour
with difference greater than 1. If such digit is found, the number is non-jumbled.
Below is the implementation of above idea :
C++
// CPP code to check if a // number is jumbled or not #include <bits/stdc++.h> using namespace std; // Function to check if a // number is jumbled or not bool checkJumbled(int num) { // Single digit number if (num / 10 == 0) return true; // Checking every digit // through a loop while (num != 0) { // All digits were checked if (num / 10 == 0) return true; // Digit at index i int digit1 = num % 10; // Digit at index i-1 int digit2 = (num / 10) % 10; // If difference is // greater than 1 if (abs(digit2 - digit1) > 1) return false; num = num / 10; } // Number checked return true; } // Driver code int main() { //-1234 to be checked int num = -1234; if (checkJumbled(num)) cout << "True \n"; else cout << "False \n"; // 287 to be checked num = -1247; if (checkJumbled(num)) cout << "True \n"; else cout << "False \n"; return 0; } |
Java
// Java code to check if a // number is jumbled or not import java.io.*; class GFG { // Function to check if a // number is jumbled or not static boolean checkJumbled(int num) { // Single digit number if (num / 10 == 0) return true; // Checking every digit // through a loop while (num != 0) { // All digits were checked if (num / 10 == 0) return true; // Digit at index i int digit1 = num % 10; // Digit at index i-1 int digit2 = (num / 10) % 10; // If difference is // greater than 1 if (Math.abs(digit2 - digit1) > 1) return false; num = num / 10; } // Number checked return true; } // Driver code public static void main (String[]args) { //-1234 to be checked int num = -1234; if (checkJumbled(num)) System.out.println("True "); else System.out.println("False "); // 287 to be checked num = -1247; if (checkJumbled(num)) System.out.println("True "); else System.out.println("False "); } } // This code is contributed by vt_m. |
