Code the given problem using python
Pishty is a little boy who lives in Khust, an ancient town with a castle and smart
bears. Right now, he wants you to help him with a programming problem.
You are given a sequence A1, A2, .., n and Q queries. There are two types of
queries:
• 1 pos val – Set Apos = val.
• 21r- Find the maximum possible perimeter of a triangle with non-zero area
whose sides are elements of the subsequence Aj, Aj+1, . Ar. Note that each
element of the subsequence can only be used as the length of at most one
side, i.e. the sides of each valid triangle must be elements Ax, Ay, Az, where I
Sx <y <zśr.
For each query of the second type, compute the maximum possible perimeter or
determine that no valid triangle exists.
Input:
