Question

Each string in an array is a number, for example array1 = ["1296", "12", "27"];

For each string above, if possible to divide by 6 evenly without remainders, I want to do so at least once, then if the result is still longer than 2 characters, repeat. Then replace the string in the same position, such that the array would become ["36", "2", "27"];

so far, my code partly works.

w=0;
function divideBySix(){
            if ((array1[w] / 6) == (Math.floor(array1[w] / 6))) {
            var temp = array1[w] / 6;
            array1[w] = temp.toString();
            if (array1[w].length < 3) {
                w++;
            }
            divideBySix();
    }

The function successfully divides the first string by 6 once, and then calls itself again and again until the result is within 2 chars long. At that point, it should continue calling itself, and do the same to the next string of the array. But it doesn’t do the next string. I don’t know why it stops after finishing the first string. So the array looks like this ["36", "12", "27"]; Also, w successfully gets incremented. So I know its getting at least that far…

Answer 1

The function you give has unbalanced { }. When I add one at the end and run it, I get the result you say you want — ["36", "2", "27"]. There must be something else wrong, or you have not copied the code correctly.

In order to understand the operation, I added this to the beginning of divideBySix:

console.log(w, array1.toString());
