Longest Winning Streak

Your team's season is one long story of W's and L's. 🏆

You get the season as a list of results, each W or L. Print the longest run of W's in a row (0 if the team never won).

Example:

Input: results = ["W", "W", "L", "W", "W", "W", "L"] Output: 3

The streaks are W,W (length 2), then a reset, then W,W,W (length 3) — the longest is 3.
