Problem Statement

In the Ancient Kingdom of Snuke, there was a pyramid to strengthen the authority of Takahashi, the president of AtCoder Inc.

The pyramid had center coordinates (C_X, C_Y) and height H. The altitude of coordinates (X, Y) is max(H - |X - C_X| - |Y - C_Y|, 0).

Aoki, an explorer, conducted a survey to identify the center coordinates and height of this pyramid. As a result, he obtained the following information:

C_X, C_Y was integers between 0 and 100 (inclusive), and H was an integer not less than 1.

Additionally, he obtained N pieces of information. The i-th of them is: "the altitude of point (x_i, y_i) is h_i."

This was enough to identify the center coordinates and the height of the pyramid. Find these values with the clues above.

Constraints

N is an integer between 1 and 100 (inclusive).

x_i and y_i are integers between 0 and 100 (inclusive).

h_i is an integer between 0 and 10^9 (inclusive).

The N coordinates (x_1, y_1), (x_2, y_2), (x_3, y_3), ..., (x_N, y_N) are all different.

The center coordinates and the height of the pyramid can be uniquely identified.

Input

Input is given from Standard Input in the following format:

N
x_1 y_1 h_1
x_2 y_2 h_2
x_3 y_3 h_3
:
x_N y_N h_N

Output

Print values C_X, C_Y and H representing the center coordinates and the height of the pyramid in one line, with spaces in between.

Sample Input 1

4
2 3 5
2 1 5
1 2 5
3 2 5

Sample Output 1

2 2 6

In this case, the center coordinates and the height can be identified as (2, 2) and 6.

Sample Input 2

2
0 0 100
1 1 98

Sample Output 2

0 0 100

In this case, the center coordinates and the height can be identified as (0, 0) and 100.

Note that C_X and C_Y are known to be integers between 0 and 100.

Sample Input 3

3
99 1 191
100 1 192
99 0 192

Sample Output 3

100 0 193

In this case, the center coordinates and the height can be identified as (100, 0) and 193.

Solution in Kotlin (1.0.0) (judge verdict: Wrong Answer)

fun main(args: Array<String>) {
    val n = readLine()!!.toLong()
    val data = mutableMapOf<Pair<Long, Long>, MutableList<Long>>()
    var count = 0
    for (i in 1..n) {
        val (x, y, h) = readLine()!!.split(' ').map(String::toLong)
        if (h != 0L) {
            count++
            for (xi in 0..100) {
                for (yi in 0..100) {
                    if (data[Pair(xi.toLong(), yi.toLong())] == null) {
                        val list = mutableListOf<Long>()
                        list.add(h + Math.abs(xi - x) + Math.abs(yi - y))
                        data[Pair(xi.toLong(), yi.toLong())] = list
                    } else {
                        data[Pair(xi.toLong(), yi.toLong())]!!.add(h + Math.abs(xi - x) + Math.abs(yi - y))
                    }
                }
            }
        }
    }
    val filterValues = data.filterValues { it.groupBy { it }.maxBy { it.value.size }!!.value.size == count }
    for (v in filterValues) {
        println("${v.key.first} ${v.key.second} ${v.value[0]}")
    }
