整数

// 定义并初始化一个包含10个整数的数组
const numbers = [5, 10, 3, 8, 15, 2, 7, 12, 9, 4];

// 初始化变量
let sum = 0;
let max = numbers[0];
let min = numbers[0];

// 遍历数组并计算总和、最大值和最小值
for (let i = 0; i < numbers.length; i++) {
    sum += numbers[i];

    if (numbers[i] > max) {
        max = numbers[i];
    }

    if (numbers[i] < min) {
        min = numbers[i];
    }
}

// 输出结果
console.log("数组元素:", numbers);
console.log("总和:", sum);
console.log("最大值:", max);
console.log("最小值:", min);
