Python Guide (pypy3)

Python submissions run with pypy3. Output checking is case-insensitive unless the problem statement says otherwise.

Judge Assumptions

• Use stdin and stdout only.
• No file I/O and no network access.
• For interactive problems, flush after each command.
• All supported languages are calibrated for fairness.

Fast Input Patterns

import sys

data = sys.stdin.readline().strip().split()
a = int(data[0])
b = int(data[1])
print(a + b)

import sys

n = int(sys.stdin.readline())
arr = list(map(int, sys.stdin.readline().split()))
print(sum(arr))
