Provide tags and a correct Python 3 solution for this coding contest problem.
A median of an array of integers of length n is the number standing on the ⌈ {n/2} ⌉ (rounding up) position in the non-decreasing ordering of its elements. Positions are numbered starting with 1. For example, a median of the array [2, 6, 4, ... | instruction | 0 | 54,148 | 12 | 108,296 |
Tags: greedy, math
Correct Solution:
```
import math
for _ in range(int(input())):
data = list(map(int, input().split()))
n, k = data[0], data[1]
numbers = list(map(int, input().split()))
median = math.ceil(n/2) -1
total = 0
if n<=2:
for i in range(k):
total += numbers[median... | output | 1 | 54,148 | 12 | 108,297 |
