Problem type

Canadian Computing Competition: 2011 Stage 1, Senior #2

Your teacher likes to give multiple choice tests. One benefit of giving these tests is that they are easy to mark, given an answer key. The other benefit is that students believe they have a one-in-five chance of getting the correct answer, assuming the multiple choice possibilities are A, B, C, D or E.

Write a program that your teacher can use to grade one multiple choice test.

Input Specification

The input will contain the number $N$ $N$ $(0 < N < 10\,000)$ $(0 < N < 10 000)$ followed by $2N$ $2 N$ lines. The $2N$ $2 N$ lines are composed of $N$ $N$ lines of student responses (with one of A, B, C, D or E on each line), followed by $N$ $N$ lines of correct answers (with one of A, B, C, D or E on each line), in the same order as the student answered the questions (that is, if line $i$ $i$ is the student response, then line $N+i$ $N + i$ will contain the correct answer to that question).

Output Specification

Output the integer $C$ $C$ $(0 \le C \le N)$ $(0 \leq C \leq N)$ which corresponds to the number of questions the student answered correctly.

Hey everyone, use AI to understand the question, not just to look for the answer. Ask the AI for explanations—it helps me a lot.

Why are problems in this website written so terribly? This one in particular made me want to tear my hair out. Unreal...

I do not understand why I am getting an IndexError when I run this in the solution. It works just fine in VSCode

I'm getting the same IndexError and my code works fine in Mu Editor. Were you able to figure out what was going wrong?
