P8891 "UOI-R1" Query
Background
ZSS has a sequence, but he is not very smart, so he comes to ask you even about an operation problem.
Description
Given an integer sequence of $n$ numbers $a_1, a_2, \cdots, a_n$, there are $m$ operations. In each operation, $x, y$ are given. You need to find all $i$ such that $i \oplus x = 0$, and then do $a_i \gets a_i - y$. If there is no such $i$, then the sequence will not be changed. Here, $\oplus$ denotes the bitwise XOR operation.
After all operations are finished, you need to output this sequence.
Input Format
The first line contains two positive integers $n, m$, representing the length of the sequence and the number of operations.
The next line contains the initial sequence.
The next $m$ lines each contain two numbers $x, y$, with the meaning as described above.
Output Format
Output one line with $n$ numbers, representing the sequence after all operations.
Explanation/Hint
For $20\%$ of the testdata, it is guaranteed that $1 \leq n, m \leq 10^3$.
For another $20\%$ of the testdata, it is guaranteed that $x = 0$.
For $100\%$ of the testdata, it is guaranteed that $1 \leq n, m \leq 10^6$, $-10^8 \leq y, a_i \leq 10^{8}$, and $0 \leq x \leq n$.
