Daily Challenge #37 - Name Swap

In today's challenge, we ask that you to write a function that returns a string in which an individual's first name is swapped with their last name.

Example: nameShuffler('Emma McClane'); => "McClane Emma"

Good luck!

JavaScript:

function nameShuffler(str){
  return str.split(' ').reverse().join(" ");
}

Here is the simple solution with Python:

def name_shuffler(string):
    string_array = string.split(' ')

    return string_array[1] + ' ' + string_array[0]

My solution in js

const nameShuffler = (name) => `${name}`.split(' ').reverse().join(' ');

[Craig McIlwrath]

nameShuffler = unwords . reverse . words

Seems pretty simple (Haskell)

 <?php

 echo implode(' ', array_reverse(explode(' ', $argv[1])));

Python :

def name_shuffler(name): return ' '.join([name.split()[1], name.split()[0]])

Buffer goes buf-buf

const rename = name => {
    const inBuf = Buffer.from(name, 'utf8')
    const len = inBuf.length
    const outBuf = Buffer.alloc(len, 0x20)
    let prev = 0
  for (let i = 0; i < len; i++) {
    if (inBuf[i] !== 0x20) continue
    inBuf.copy(outBuf, len - i, prev, i)
    prev = i + 1
  }
  inBuf.copy(outBuf, 0, prev)
    return outBuf.toString('utf8')
}

Nice and simple python implementation 😁

def nameShuffler(name):
    name = name.split()
    name.reverse()
    print(str(name))

There is my python solution

Rust Playground

fn name_shuffler(name: &str) -> String {
    name.split_whitespace().rev().collect::<Vec<&str>>().join(" ")
}
