I have only put 1 condition in second case for if map[x] > 0 then execute the code.
let result = []; let freq = []; let map = {}; for (let i = 0; i < queries.length; i++) { const [op, x] = queries[i]; const f = map[x] || 0; if (op === 1) { map[x] = f + 1; freq[f] = (freq[f] || 0) - 1; freq[f + 1] = (freq[f + 1] || 0) + 1; } if (op === 2) { if (map[x] > 0) { map[x] = f - 1; freq[f - 1] += 1; freq[f] -= 1; } } if (op === 3) { result.push(freq[x] > 0 ? 1 : 0); } } return result;
