Mobile coding works. A laptop is faster for long sessions.
Problem
A tree with `n` nodes numbered from `1` to `n` is represented by
the parent array `t`, where `t[i]` is the parent of node `i`, and
`t[i] = 0` means that node `i` is the root of the tree.
An additional natural number `x` with `1 <= x <= n` is also read. Print,
in ascending order, the indices of the direct children of node `x`.
If node `x` has no direct children (it is a leaf), print the word
`frunza` (no diacritics).
Input format
Input
input.txt
The first line contains two natural numbers `n` and `x`, separated by a space. The second line contains the `n` values of the parent array, separated by spaces. - `1 <= n <= 100` - `1 <= x <= n` - the array describes a valid tree

Output
output.txt
The program prints the direct children of node `x` in ascending order, separated by spaces. If node `x` is a leaf, the program prints `frunza`.
