Left Rotation

  • smanne + 3 comments

    No need of loops, here is my solution in js

    function processData(input) {
    //Enter your code here
    let linesArray = input.split("\n");
    let line1 = linesArray[0].split(' ');
    let numberOfInt = line1[0];
    let numberOfRotations = line1[1];
    let integers = linesArray[1].split(' ');
    array1 = integers.slice(0, numberOfRotations);
    array2 = integers.slice(numberOfRotations, numberOfInt);
    console.log(array2.concat(array1).join(' '));
}

      Smooth! In PHP: 

      <?php
function rotLeft(`$a, $`d) {
    `$array1 = array_slice($`a, `$d, count($`a));
    `$array2 = array_slice($`a, 0, $d);
return array_merge(`$array1, $`array2);
}

      I had the same solution. Under the hood, this does use loops, though.
