Get palindrome

Demo Code


var op = {//from w  ww  .j  ava 2  s  .co m
    palindrome: function(x, y) {
        var result = 0;
        var x_min = Math.pow(10, x - 1),
        x_max = Math.pow(10, x),
        y_min = Math.pow(10, y - 1),
        y_max = Math.pow(10, y);

        for (i = x_min; i < x_max; i++) {
            for (j = y_min; j < y_max; j++) {
                number = i * j;
                number_string = "" + number;
                number_reversed = number_string.reverse();
                if (number_string == number_reversed && number > result) {
                    result = number;
                }
            }
        }

        return (result > 0) ? result: "No Palindrome";
    }
