### Prompt

Develop a solution in Cpp to the problem described below:

problem

Given the formula $ S $ of length $ N $. The formula is in the format shown in BNF below.


<expr> :: = <number> | <expr> <op> <expr>

<op> :: = ‘^’ | ‘&’ | ‘|’



<number> represents an integer greater than or equal to $ 0 $ and less than or equal to $ 2 ^ {31} -1 $.

The operators ‘^’ ‘&’ ‘|’ represent exclusive OR, AND, and OR, respectively. The precedence of operators is as follows.

High ‘^’> ‘&’> ‘|’ Low

$ Q $ intervals $ [i, j] $ are given. Output the calculation result of $ S_i, \ dots, S_j $.

It is guaranteed that the formulas $ S_i, \ dots, S_j $ are in the format shown by the above BNF. Also, the formula does not contain zero-padded values.



output

Output the calculation result of $ S_i, \ dots, S_j $. Also, output a line break at the end.
