The first line of input contains two integers nn and qq (1n,q1061≤n,q≤106) — the length of array aa and the number of queries you have to perform.

Each of the next qq lines contains the query given in the form described in the problem statement.

Output

Print the answers to the queries of the third type on separate lines.
