MEX queries

Revision en3, by _greg, 2017-10-20 05:22:57

I have heard about the problem with this statement:

You are given an integer array. You need to perform two types of queries:

1. " pos val " — assign val to position pos.

2. " l r " — find MEX on the segment from l to r.

Does anyone know where can this problem be found?
