problem is this.
https://codeforces.net/contest/1003/problem/F
i can't understand why the answer for test case below is 5
3 abcdef abcdef abcdef
my program (and i ) think A abcdef A is optimal so output 10
vovuh's solution output 5.
how 5 is possible? since we should select non-intersecting segments, at least one abcdef should remain and the answer must >=6. need help for this.
i think it's ok to choose three words,so the answer can be 'A A A'.
I hope i haven't made mistakes because of my poor English.
oh i thought i should select exactly 2 segments of any length. i'll try out choosing several segments. thank you
