    /*
     * LOGIC : Eliminate a digit from the number given and count that in no_of_digits
     * EXAMPLE : If '1356' is a number, the count follows this below process 
     * --> 1356/10 = 135 : Count = 1
     * --> 135/10  = 13  : Count = 2
     * --> 13/10   = 1   : Count = 3
     * --> 1/10    = 0   : Count = 5
     * --> 0 doesn't satisfy the loop condition, so it exits the loop
