/**about

SheLogN is a daily DSA channel. The name is a wink at log n: the efficient way to learn is a little every day, not a lot once.

Each video takes one problem from the Top Interview 150, walks through the brute force, finds the insight, and writes the clean solution. About ten minutes, no filler.

Started 13 Oct 2026. Day by day, until all 150 are done.
