for循环用于迭代字符串的一半。if条件用于检查第一个和相应的最后一个字符是否相同。这个循环一直持续到字符串的一半为止。 在迭代过程中,如果字符串的任何字符与其对应的最后一个字符串不相等,则该字符串不被视为回文。 示例2:使用内置函数检查回文 // program to check if the string is palindrome or notfunctio...
JavaScript exercises, practice and solution: Write a JavaScript program to find the shortest possible string. This can be converted into a string and converted into a palindrome by adding characters to the end of it.
// program to check if the string is palindrome or not functioncheckPalindrome(str){ // find the length of a string constlen = string.length; // loop through half of the string for(leti =0; i < len /2; i++){ // check if first and last string are same if(string[i]!== stri...
97. Shortest String to Convert into Palindrome Write a JavaScript program to find the shortest possible string. This can be converted into a string and converted into a palindrome by adding characters to the end of it. Click me to see the solution ...
11. Palindrome A palindrome is a string or number that looks exactly the same when it is reversed. For example: abba, 121, etc. const isPalindrome = str => str === str.split('').reverse().join(''); result = isPalindrome('abcba'); console.log(result) --- true result = isPalin...
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...

function isPalindrome(str) { str = str.replace(/\W/g, '').toLowerCase(); //removes all non-word character return (str == str.split('').reverse().join('')); //remove space, reverse, and check }For example:console.log(isPalindrome("level")); // logs 'true' console.log(is...
