Jumbled Numbers JavaScript | In this post, we will see a program to check whether the given number is a Jumbled number or not in JavaScript.
A Jumbled number is one in which the neighboring digits (on the left or right) deviate by at least one value. This article will help you learn how to deal with Jumbled numbers in JavaScript. Here are a few examples that will help you understand the jumbled numbers in JavaScript.
Example 1:
number- 12345
Is it a Jumbled number?
True
Example 2:
7898
Is it a Jumbled number?
True
Example 3:
87582
Is it a Jumbled number?
False
Example 4:
2439
Is it a Jumbled number?
False
Steps To Find Out Jumbled Numbers In JavaScript
1. For a program in JavaScript to find jumbled numbers, first declare the function.
2. Using the if-else and while loop, parse each digit and check whether or not their adjacent values are greater than one.
3. Declare two conditions for digit at “i” and at [i-1].
4. Use the if loop for conditions where the difference is greater than 1.
5. Check whether the conditions are satisfied.
6. Take inputs or declare the numbers you want to check. Then give a condition using an if-else loop, where it is True when the numbers are jumbled or False when the numbers are not jumbled.
Program To Find Out Jumbled Numbers JavaScript
// Jumbled numbers in JavaScript
// Function declaration
function checkJumbled(n) {
// for single digit number
if (parseInt(n / 10, 10) == 0)
return true;
// parsing each digit via loop
while (n != 0) {
//checked
if (parseInt(n / 10, 10) == 0)
return true;
// number present at index i
let digit1 = n % 10;
// number present at index i-1
let digit2 = parseInt(n / 10, 10) % 10;
// if loop for conditon where the
// difference is greater than 1
if (Math.abs(digit2 - digit1) > 1)
return false;
n = parseInt(n / 10, 10);
}
// number checked
return true;
}
// lets check 6789
let n = 6789;
if (checkJumbled(n))
console.log("True");
else
console.log("False");
// lets check 1247
n = 1247;
if (checkJumbled(n))
console.log("True");
else
console.log("False");
Output:-
True
False
The number 6789 is a Jumbled number because neighboring digits deviate by at least one value whereas the number 1247 is not a Jumbled number because neighboring digits are not deviated by at least one value. Also see:- JavaScript Remove Last Digit from Number
