Sample input available Sample output available

Editor

Python

Hints

Process the file line by line instead of reading it all at once.

Solution explanation

Iterating over a file streams it, so even huge files use little memory.

Show solution

with open("input.txt", "w") as f:
    while (line := input()) != "EOF":
        f.write(line + "\n")

lines = words = chars = 0
with open("input.txt") as f:
    for line in f:
        line = line.rstrip("\n")
        lines += 1
        words += len(line.split())
        chars += len(line)
print(lines, words, chars)

Output
