// Function to check if a given string is a palindrome using recursion function isPalindrome(str) { // Base case: if the string has 0 or 1 characters, it's a palindrome if (str.length <= 1) { return true; } // Check if the first and last characters are equal if (str[0] !=...
constvalue =checkPalindrome(string); console.log(value); 现在,让我们看看同样的代码在被简化后的样子: functioncheckPalindrome(n){constt=string.length;for(letn=0;n<t/2;n++) if(string[n]!==string[t-1-n])return"It is not a palindrome";return"It is a palindrome"} conststring=prompt("Ent...
Step 1: We have to find out if the given string is a palindrome or not. So to do this task we will create a function called isPalindrome and in this function, we will pass a parameter of string as str. So for this str, we will check the palindrome condition. Step 2: After the...
Here, we are going to learn how to check whether a given number is palindrome or not in JavaScript.
Another method to check if a string is a palindrome or not is by using aforloop. Below are the steps to check if a string is a palindrome in JavaScript. functionpalindromeFn(string){conststringLength=string.length;for(leti=0;i<stringLength/2;i++){if(string[i]!==string[stringLength-1...
Check for Palindrome function isPalindrome(str) { return str === str.split('').reverse().join(''); } console.log(isPalindrome("racecar")); // Output: true Write a function to calculate the factorial of a number. function factorial(n) { if (n === 0 || n === 1) { return...
2. Check Palindrome Write a JavaScript function that checks whether a passed string is a palindrome or not? A palindrome is word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. Click me to see the solution ...
