CF 1058202023_2B - An Array of Characters and Almost Palindromes

We are given a fixed lowercase string and many range queries. For a query [l, r], consider the substring t = s[l..r]. Among all substrings of t, we want the maximum length of a substring that is not a nearly palindrome.

CF 1058202024_2A - Colorful Table

We are given an n × m grid whose cells contain colors. The available colors are either {R, G} when c = 2, or {R, G, B} when c = 3. The goal is to modify at most q cells so that no two neighboring cells, horizontally or vertically, have the same color.
