function solution(cacheSize, cities) { const HIT = 1, MISS = 5 const cache = [] let totalTime = 0 if (cacheSize === 0) return MISS * cities.length for (let i = 0; i = cacheSize) { cache.shift() } } cache.push(searchTarget) } return totalTime}

1. indexOf로 배열자체의 위치를 바꿨다가 시간초과되고... (‼️)2. Map으로 풀었다. function solution(players, callings) { const playerIndexes = {}; players.forEach((player, index) => { playerIndexes[player] = index; }); callings.forEach(name => { const currentPlayerPosition = playerIndexes[name]; const prevPlayer = players[currentPlayerPosition - 1]; players[currentPlayerPosition] = ..
