将十进制转换为任意基数(使用base>=10的switch语句)

function decimalToBase(decimal, base) {
    if (base < 2 || base > 36) {
        throw new Error('Base must be between 2 and 36');
    }

    let result = '';
    const digits = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';

    while (decimal > 0) {
        let remainder = decimal % base;
        result = digits[remainder] + result;
        decimal = Math.floor(decimal / base);
    }

    return result || '0';
}

// 使用switch语句处理大于等于10的基数
function convertWithSwitch(decimal, base) {
    let result;
    switch (base) {
        case 10:
            result = decimal.toString();
            break;
        case 11:
            result = decimalToBase(decimal, 11);
            break;
        case 12:
            result = decimalToBase(decimal, 12);
            break;
        // ... 可以继续添加更多的case来处理其他基数
        case 36:
            result = decimalToBase(decimal, 36);
            break;
        default:
            throw new Error('Unsupported base');
    }
    return result;
}

// 示例使用
console.log(convertWithSwitch(15, 16)); // 输出 "F"
console.log(convertWithSwitch(255, 16)); // 输出 "FF"
