Given two non-negative int values, return true if they have the same last digit, such as with 27 and 57. Note that the % “mod” operator computes remainders, so 17 % 10 is 7.

lastDigit(7, 17) ? true
lastDigit(6, 17) ? false
lastDigit(3, 113) ? true

public boolean lastDigit(int a, int b) {
if(a%10 == b%10) return true;
else return false;
}
