I-th (4) P74859

Write a program that, given several test cases, each one composed by an integer number $i$ and a sequence of natural numbers $x_1, x_2, \dots, x_n$, prints each $x_i$.

Input

Input has several cases. Each case begins with an integer number $i$, followed by a sequence $x_1, \dots, x_n$ ended with $-1$.

Output

For each case, if the position $i$ is correct, print the content of $i$ as it is shown in the examples. Otherwise, print “Incorrect position.”.
