Why don't you read the editorial http://codeforces.me/blog/entry/8903
I read it but I didn't understand the logic behind it.So thought someone would explain it in simple way.
dp[i][j][k] : max { length(s) : s is LCS of s1[0,i[ and s2[0,j[, suffix of s and virus share k chars }.
use KMP to do the state transition.
Thanks.got some clarity now.
