Problem Link: CodeChef: Practical coding for everyone
There are a few problems with your code. First, never output anything that isn’t specified by the problem otherwise it will be marked wrong. In this case, passing an argument to the input function on lines 2 and 4 will output said string. Remove those arguments. Second, n denotes the number of test-cases. Each test-case has its own set of data and therefore its own output. You are only printing once, which means instead of say 3 outputs for 3 test-cases, you only have one. There are two ways to fix your code (assuming you addressed the first issue). You could:
// your code above
for i in a:
print(i)
The problem is that print(a) will print the entire array. That means your output would look something like: [answer_1, answer_2, anwer_3, ..., answer_n] (where answer_i is the i-th test-cases answer) and will not look like what is required:
answer_1
answer_2
answer_3
...
answer_n
The code above aims to solve this.
print(a) and a.append(cold), and instead, print(cold) inside the for loop right after you set cold = temperature[1]. This makes a useless and also allows you to output the answer right after computation (instead of waiting till the end and then printing all the elements of a)Other than that, your algorithm looks right.
