The question I was solving is Room Allocation,on codechef but i get a Value Error and I try to fix it but i dont get it.

import math
t=int(input())
for i in range(t):
n=int(input())
s=0
for j in range(n):
a=int(input())
half=a//2
s=s+half
print(s)

You mean Room Allocation problem?

It’s impossible to know what it happening in your code due you are using Python and you are sharing it without indentation.

My guess is that you are doing this:

import math
t=int(input())
for i in range(t):
    n=int(input())
    s=0
    for j in range(n):
        a=int(input())
        half=a//2
        s=s+half
    print(s)

Input values. You are receiving the A array like if it was an only integer. That throws a ValueError because your int() cast is trying to cast whitespaces into integers.

You are doing this:

a = int(input())

When you should be doing this:

a = list(map(int, input().split())

In Python, when you get the single line of integers, you should use input().split() to get the complete list. So your code should be:

import math
t=int(input())
for i in range(t):
    n=int(input())
    a = list(map(int, input().split())
    s=0
    for j in range(n):
        # Choose a way to access your list
        half= ( ... )//2
        s=s+half
    print(s)

That will solve your Value Error problem.
