7604: [CSES Problem Set] Range Update Queries
[Creator : ]
Description
Given an array of $n$ integers, your task is to process $q$ queries of the following types:
-
increase each value in range $[a,b]$ by $u$
- what is the value at position $k$?
Input
The first input line has two integers $n$ and $q$: the number of values and queries.
The second line has $n$ integers $x_1,x_2,\dots,x_n$: the array values.
Finally, there are $q$ lines describing the queries. Each line has three integers: either "1 a b u" or "2 k".
The second line has $n$ integers $x_1,x_2,\dots,x_n$: the array values.
Finally, there are $q$ lines describing the queries. Each line has three integers: either "1 a b u" or "2 k".
Output
Print the result of each query of type 2.
