https://codeforces.me/problemset/problem/1339/B Hello, i am getting runtime error on this...Can anyone help me out..when i test samples on my own laptop, it is working out fine!!
T = int(input())
for s in range(1,T+1):
N = int(input())
l = [int(input()) for i in range(N)]
l.sort()
p = []
x = len(l)
while (len(l)>2):
p = [l[0],l[-1]] + p
l = l[1:-1]
p = l + p
print(*p,sep=" ")
This is failing because
l = [int(input()) for i in range(N)]is not a valid way to take a line of input in python (the input() function returns the entire line, which cannot be turned into an int).The correct way to do this is the code
l = list(map(int,input().split())).
