You will have to perform operations on this array. There will be two types of operations:
In the first line of input, there will be two integers and (, ) which are the length of the array and number of operations to perform respectively.
Next Q lines will contain the description of the operations to perform in the format or (, ).
For each operation of the format , print the answer of the query in a single line.
