Algorithm to rotate an array in linear time

Question

How to rotate an integer array by i times using swap function only in linear time.

Answer 1

here is my answer using js hope this helps where k is the number of the rotations you want to preform

 var arrayRoatate=function(array,k){
    for(;k>0;k--) {
     var nextElementValue=undefined;
        for (var i = 0; i < array.length; i=i+2) {
            var nextElement = i + 1;
            if (nextElement >= array.length)
                nextElement = nextElement - array.length;
            var tmp=array[i];
            if(nextElementValue!==undefined)
                array[i]=nextElementValue
            nextElementValue=array[nextElement];
            array[nextElement]=tmp;

        }
    }
return array;
