WebA property of integers was described, that of being a self-divisor (when every digit of the number evenly divides the number). In part (a) students were required to implement the isSelfDivisor method for determining whether a given number is a self-divisor. WebA positive integer is called a "self-divisor" if every decimal digit of the number is a divisor of thenumber, that is, the number is evenly divisible by each and every one of its digits. For example,the number 128 is a selfdivisor because it is evenly divisible by 1, 2, and 8.
