what is the code of digit extraction hashing function in c++?

[deerlittle7]

The distribution of

this hashing function is dependent on the distribution of the key

values. the key values are analyzed to determine which digit positions

of the key are more evenly distributed. the more evenly distributed

digit positions are assigned from right to left. the digit values in the

chosen digit positions are extracted, and the resulting integer is used

as the relative address. if none of the digit positions has a uniform

distribution, more collisions occur.
example:
enter number:265791353
enter number of digit places:1-3-5-7/*this is the position of the number

in the number:25936 which is : 2 5 9 3 in which:1st(2) 3rd(5) 5th(9) 7th

(3)*/
the other numbers in the number:265791353 will be added in the first

number:2593 which is:6715 (2nd(6) 4th(7) 6th(1) 8th(5))//
2593+6715;
answer is:
9308
then get the last two digits as the final answer:
08
