2. Copy the following contents:

Template File - CPP

Call this t.cpp in the root directory for later use.

// Team Name (Monash)
#include <bits/stdc++.h>
using namespace std;

#define me (*this)
#define debug(a) cerr << #a << " = " << (a) << endl;
#define pb(a) push_back(a)
#define mp(a,b) make_pair(a,b)
typedef long long ll;
typedef pair<int, int> pii;

int main() {
    ios::sync_with_stdio(0); cin.tie(0);

    return 0;
}

Template File - Python

Call this t.py in the root directory for later use.

# Team Name (Monash)

def read_ints():
    return list(map(int, input().split()))

cases = int(input())

for case in range(cases):
    # Do something.

Generate folders and template files

Run this in terminal once:

for i in {A..R}; do
    # Create subdir
    mkdir $i
    # Copy templates
    cp t.cpp $i/$i.cpp
    cp t.py $i/$i.py
    # Provided samples are downloaded, extract them.
done
