In the first line there is an integer N (N = 100000) Each query is represented by two numbers L and R, and it asks you to compute some function Func with subarray Arr[L..R] as its argument.. For the sake of brevity we will denote Func([L, R]) as the value of Func on subarray Arr[L..R]. Each instance begins with a line containing two integers, 1<= n<= 100 and m .
