[LBA-OI R1 D] 单挑风云

Background

During the LBA playoffs, two trainers, Alice and Bob, from the Martian Cats training camp will select two players from the player list for a one‑on‑one duel to test their skills.

Problem Description

Alice and Bob first find an integer sequence of length nn, where each number lies in [0,2W1][0, 2^W-1], representing the data of nn players.

For a test of the form L,RL,R, the current player data list is the interval [L,R][L,R] of the original list.

For each test, Alice and Bob will choose players to duel.

::::info[Duel Rules]{open}

  • Alice chooses first, Bob chooses second, and Bob knows what Alice chose. Let the indices chosen by the two players from the list be ii and jj respectively, and the corresponding player data be ai,aja_i, a_j (it is allowed to choose the same player, i.e., i=ji=j is legal).
  • The duel index pp is defined as aiaja_i \oplus a_j, where \oplus denotes the bitwise XOR operation.
  • Alice wants to minimize pp, while Bob wants to maximize pp. ::::

Now Alice and Bob are both extremely clever and both use optimal strategies.

For each test L,RL,R, let pp be the duel index resulting from the optimal choices of Alice and Bob. The answer for this test is the highest bit position where pp has a 00 in its binary representation.

::::warning[Example and Details]

We define the lowest bit position as 00, and you only need to consider bit positions from 00 to W1W-1.

For example, if p=(11010101)2p = (11010101)_2:

bit position: 7 6 5 4 3 2 1 0
value:        1 1 0 1 0 1 0 1

Then the answer is 55.

If p=2W1p = 2^W-1, meaning all bits are 11, then the answer is 1-1. ::::

Now you need to perform qq operations, each of the form l,r,dl, r, d.

For each operation, you need to answer: among all subintervals of [li,ri][l_i, r_i], using each subinterval as the player list for a test, how many tests have an answer d\le d.


Formal Definition

Given a positive integer WW and a sequence a1,a2,,ana_1, a_2, \ldots, a_n, where each aia_i is an integer in [0,2W)[0, 2^W) (i.e., each aia_i is a WW-bit unsigned integer).
For any subinterval [L,R][L, R] (with 1LRn1 \le L \le R \le n), define the function ans(L,R)\text{ans}(L, R) as follows:

  • Alice and Bob play a game. Alice moves first, and both choose an index from the interval [L,R][L, R].
  • Alice chooses index i[L,R]i \in [L, R] to minimize aiaja_i \oplus a_j, Bob chooses index j[L,R]j \in [L, R] to maximize aiaja_i \oplus a_j (where \oplus denotes bitwise XOR).
  • Both play optimally, so $\text{ans}(L, R) = \min_{i \in [L, R]} \max_{j \in [L, R]} (a_i \oplus a_j)$.

Now, given qq queries, each query consists of three parameters l,r,dl, r, d (where 1lrn1 \le l \le r \le n and 0d1<W0 \le d-1 < W).
For each query, compute:

$$\sum_{i=l}^{r} \sum_{j=i}^{r} \left[\text{ans}(i, j) \oplus (2^W - 1) < 2^{d+1}\right]$$

where [P][P] is the Iverson bracket, equal to 11 if condition PP is true and 00 otherwise.
Note: ans(i,j)(2W1)\text{ans}(i, j) \oplus (2^W - 1) is equivalent to bitwise NOT of ans(i,j)\text{ans}(i, j) (considering WW-bit representation).
