I need make some width function. It take a string and must to return an arrive with changed letters. For example:
enter code here
let word = 'letter'
function(word) {
// code here
return var // {letter, etterl, tterle, terlet, erlett, rlette]
You can easily achieve the result if you first split the string, and then loop over the character array.
All you have to do is to push the first character at the end of the array on every iteration.
let word = 'letter';
function getResult(word) {
const wordArray = word.split('');
const result = [];
for (let i = 0; i < word.length; ++i) {
result.push(wordArray.join(''));
wordArray.push(wordArray.shift());
}
return result;
}
console.log(getResult(word));you can do this:
function permut(string) {
if (string.length < 2) return string;
const permutations = [];
for (let i = 0; i < string.length; i++) {
const char = string[i];
if (string.indexOf(char) !== i) continue;
const remainingString =
string.slice(0, i) + string.slice(i + 1, string.length);
for (const subPermutation of permut(remainingString))
permutations.push(char + subPermutation);
}
return permutations;
}
console.log(permut("hello"));
