I finally wrote a code faster, better and more destructive than the AI chatbot generated. Have a look. Python. But it is so simple you can transplant it to anything.

def climbingLeaderboard(ranked, player):

ranked = sorted(list(set(ranked)), reverse=True)
ans = []

for p in player:

    while len(ranked) > 0 and ranked[-1] < p:
        ranked.pop()

    if len(ranked) == 0:
        ans.append(1)
    elif ranked[-1] == p:
        ans.append(len(ranked))
    else:
        ans.append(len(ranked)+1)

return ans
