    Assume S1 is true. Then S2, S3, S4, S5, and S6 must all be true. But if S2 is true, it would mean that S3, S4, S5, and S6 are all false. This is a direct contradiction, so S1 must be false.

    Assume S2 is true. Then S3, S4, S5, and S6 must all be false. However, if S1 is false, S2 true, and S3 false, then exactly one of S1, S2, S3 is true (only S2 is true), which would make S4 true. This contradicts the assumption that S4 is false, so S2 must be false.

    S3 says "Both of the statements above are true." Since S1 and S2 are both false, S3 is false.

    S4 says "Exactly one of the three statements above is true." For S1, S2, and S3, all are false (0 true), so S4 is false.

    S5 says "None of the four statements above are true." We have S1, S2, S3, and S4 all false. This makes S5 true.

    S6 says "None of the five statements above are true." But since S5 is true, not all of S1–S5 are false, so S6 must be false.

    Conclusion: Only S5 is true.

Suggestion: Do you use Inclusive-Inclusive [L,R] ranges or Inclusive-Exclusive [L,R) ranges?

Suggestion 2: Do you use node-based (pointer) or array-based segment tree?

1 indexed vs 0 indexed (genuinely curious, been encouraged to 1 index moreso trying to see whats usually more common altho cf automatically 1-indexes so might be biased)

We need different option for DFS and BFS, deque for BFS and recursion for DFS.
