I get the NZEC RE error that is shown in the uploaded pic when i submit the code. Please help me out!

The problem link:

Mycode:
t=int(input())
while(t>0):
x,y,k,n=map(int,input().strip().split())
page=x-y
for j in range(n):
p,c=map(int,input().strip().split())
lc=0
if((c<=k) and (p>=page)):
lc=lc+1
break
else:
continue
if(lc>0):
print(“Luckychef”)
else:
print(“Unluckychef”)
t=t-1

You must complete the input.
But in your code, you break your loop before reading all (n) input.
That’s why your program start reading from where you left. it deserve 4 values (x, y, k, n) but it found 2 values (P, C). Input mismatching provide NZEC error.

Solution:

import sys

def main():
  t = int(sys.stdin.readline())
  
  for _ in range(t):
    x, y, k, n = map(int, sys.stdin.readline().split())
    pg = x - y
    flag = False
    for _ in range(n):
      p, c = map(int, sys.stdin.readline().split())
      
      if p >= pg and c <= k:
        flag = True
    
    print("LuckyChef") if (flag is True) else print("UnluckyChef")

if __name__ == "__main__":
  main()

Note: Use sys module for std input. It will make your program faster.

:white_check_mark: fast => sys.stdin.readline().split()
:x: slow => input().split()
