You will be given a permutation of first N natural numbers.Then you will be asked to print the smallest index of the array which contains the number between a given range(inclusive).Refer Iput-Output for more details.

Input

First line contains two integers N and Q separated by a space.

Second line contains N integers separeted by a space.(From 1 to N in any order)

Now Q line follows :Each line contains two integers A and B separated by space.

Output

You must Output exactly Q lines each containg  the answer.

Constraint:

N<=100000,Q<=100000,A<=B<=100000.

Example

Input:
2 2

nice problem .it is not that trivial to be moved in tutorial.

It's really pointless to delete "move to tutorial" comments. I'm checking new problems regardless and assessing on my own.

For now it doesn't seem that trivial for me, but I'm not to good in this type of problems. If you point out similar ones, I move this to tutorial. If there will be some comment deleting you can drop me an e-mail :)
