Let $$\alpha$$ be the number of 5 digit numbers divisible by 4 that can be formed using the digits $$0,1,2,3,4,5$$ when repetition of digits is not allowed.

Let $$\beta$$ be the number of 5 digit numbers divisible by 4 that can be formed using the digits $$0,1,2,3,4,5$$ when repetition of digits is allowed.

Find the value of $$\alpha+\beta$$ ?
