Crown the Top Performer

Intermediate

A scoreboard maps each rep to their sales total. The banner needs the name of the single highest scorer. Ties go to whichever key the map yields first.

Implement `solve(Map<String,Integer> scores)` (non-empty) to return the key with the highest value.

Examples

Input{alice=90, bob=85, cara=95}

Output"cara"

Input{solo=1}

Output"solo"

Hints

Track the best key and best value while iterating keySet().

Anonymous Apex

String solve(Map<String, Integer> scores) {
    // return the key with the highest value
    return null;
}
