Fault in Challenge Problem of 2019-May-Long


#1

Note:-I’m not sure if my claim is right.

Link to the problem:- https://www.codechef.com/MAY19A/problems/CHEFXCHG

There is a misprint in the problem-statement.

It states that:-
"Send operation will change B(a) by K/ R and will also change B(b) by K/ R. "

Which is wrong.

It should be mentioned that : -

“Send operation will change B(a) by K X R and will also change B(b) by K X R”

If this is not done, final balance will not be zero according to given sample i/o.

Only 3-days are left for the Long Challenge and I don’t know why no one mentioned this.

Please make the required changes/remove the challenge problem/extend the Long Challenge.
