index-ints – List indexing

Write a program that prints the character at position n of a given list.

Indexing integer sequences starting from 0: The number 2 is at position 3 of the sequence 16 8 4 2. The number 360 is at position 0 of the sequence 360 60 1080.

In this exercise, positions are indexed from 0. Position 0 is the first position; Position 1 is the second position; Position 2 is the third position; etc.

Input and Output

Each line of input consists of a number n, followed by n numbers, followed by number i.

For each line of input there should be a line of output with a single integer aᵢ indicating the number at position i of the input list.

Example Input

5 1 2 3 4 5 2
4 16 8 4 2 3
3 360 60 1080 0

Example Output

3
2
360
