JavaScript: Rearrange characters of a given string in such way that it will become equal to another given string
JavaScript Basic: Exercise-99 with Solution
Write a JavaScript program to check whether it is possible to rearrange the characters of a given string. This is in such a way that it will become equal to another given string.
Sample Solution:
JavaScript Code:
// Function to check if characters of str1 can be rearranged to form str2
function rearrangement_characters(str1, str2) {
// Splitting the strings into arrays of characters
var first_set = str1.split(''), // Array for characters of str1
second_set = str2.split(''), // Array for characters of str2
result = true; // Variable to store the result of rearrangement check
// Sorting the character arrays in ascending order
first_set.sort();
second_set.sort();
// Loop through the arrays to compare each character position
for (var i = 0; i < Math.max(first_set.length, second_set.length); i++) {
// Check if characters at the same position in both arrays are different
if (first_set[i] !== second_set[i]) {
result = false; // Set result to false if characters differ
}
}
return result; // Return the final result of rearrangement check
}
// Testing the function with sample strings
console.log(rearrangement_characters("xyz", "zyx")); // Example usage
console.log(rearrangement_characters("xyz", "zyp")); // Example usage
Output:
true false

Flowchart:
ES6 Version:
// Function to check if two strings can be rearranged to form each other
const rearrangement_characters = (str1, str2) => {
// Splitting both strings into arrays of characters
let first_set = str1.split(''); // Array from first string
let second_set = str2.split(''); // Array from second string
let result = true; // Initializing result as true
// Sorting both arrays
first_set.sort();
second_set.sort();
// Looping through the arrays to compare elements
for (let i = 0; i < Math.max(first_set.length, second_set.length); i++) {
if (first_set[i] !== second_set[i]) {
result = false; // If any character at the same index is different, set result to false
}
}
return result; // Return the result
}
console.log(rearrangement_characters("xyz", "zyx")); // Example usage
console.log(rearrangement_characters("xyz", "zyp")); // Example usage
