I have WA test 12!
My algorithm is simple.
Please,tell algorithm.

I got WA on test 13 ....

Can anyone give me some testdata or tell me some trick about the test data. I have checked my program again and again .I can't find any more mistacks from my program.

Yeah! I got AC at last!

There is a very tricky test!!!!! if n = 1 , i will output

Cost : -1
Cost : -1

but the correct solution is

Cost : 0
Cost : -1

but the description tell us that N >= 2 !!!!
