need help for div.3 problem
problem is this.
https://mirror.codeforces.com/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.
