You are given a sequence of length $$$n$$$ and the number $$$k$$$, ask for support $$$m$$$ operations or inquiries:
The first line contains three integer $$$n$$$, $$$m$$$ and $$$k$$$ $$$(1\leq n,m\leq 5\times 10^5)$$$.
The next line contains $$$n$$$ integers representing the sequence $$$a$$$ $$$(1\leq a_i\leq 10^{18})$$$.
Each of the following $$$m$$$ lines contains a character and an integer, indicating an operation or inquiry.
For all data guaranteed $$$1\leq k,t\leq 10^{18},\ 1\leq x\leq n$$$.
Ensure that the sequence after each operation for all $$$a_i$$$ satisfies $$$-10^{18}\leq a_i\leq 10^{18}$$$
For each inquiry, print a line for the answer.
