Q: How do I approach Coding & Algorithms interview questions?

Coding & Algorithms questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master coding & algorithms interviews.

Question

You are given a multi-line string (via stdin) that represents the output of ls -l, with one entry per line.

Each file line follows the typical ls -l format:

<mode> <links> <owner> <group> <size> <month> <day> <time_or_year> <name...>

Task: print the file name (the <name...> part) of the entry with the largest <size>.

Requirements:

Correctly parse columns so that you read the numeric size field.
File names may contain spaces, so you cannot assume the name is a single token.
Ignore non-entry lines such as total N if present.

Output only the file name of the largest file (any tie-breaking is acceptable unless otherwise specified).
