An integer n (1 ≤ n ≤ 10^9), representing some quantity or size.
An integer m (1 ≤ m ≤ 2 × 10^5), representing some count.
Two integers x and y, both between 1 and 1e5, representing some values.
A list of m tuples. Each tuple consists of:
- An integer c (1 ≤ c ≤ 3), representing some category.
- Two integers l and r (1 ≤ l ≤ r ≤ n), representing some range.
