Class code is as follows [year][B-bachelors, M-masters, D-phd][A~D for class 清，華，梅]

as for the shortened chinese text, might be a bit of a hassle to translate?

[ImJustChew]

function makeReadable(code) {
    // Define mappings for degree types and class letters
    const degreeTypes = { 'B': '大學部', 'M': '碩士班', 'D': '博士班' };
    const classLetters = { 'A': '清班', 'B': '華班', 'C': '梅班', 'D': '班' }; // Assuming 'D' stands for a general class

    // Parse the input string
    const match = code.match(/(^[^\d]+)(\d+)([BMD])([A-D]?)/);
    if (!match) {
        return 'Invalid format';
    }

    // Extract components
    const [, deptName, year, degreeType, classLetter] = match;

    // Translate components
    const readableYear = year + '年';
    const readableDegreeType = degreeTypes[degreeType] || '';
    const readableClassLetter = classLetters[classLetter] || '';

    // Construct the output
    return `${deptName}${readableYear}${readableDegreeType}${readableClassLetter}`;
}
