JavaScript 代码：计算三个数的最大权值并输出对应字母

// 获取输入 let n = parseInt(readline()); let nums = readline().split(' ').map(Number);

// 补0 let len = n % 3 === 0 ? n : n + 3 - n % 3; while (nums.length < len) { nums.push(0); }

// 计算权值和 let sums = [0, 0, 0]; for (let i = 0; i < len; i++) { let idx = i % 3; sums[idx] += nums[i]; }

// 比较最大权值 let max = Math.max(...sums); if (max === sums[0]) { console.log('J'); } else if (max === sums[1]) { console.log('H'); } else { console.log('B'); }
