  for(int i=4 ; i<n-2 ; i++){

    Longwinded Javascript solution with switchcase and regex.

        const splitInput = input.split('\r\n');   
    const words = [];
    let formattedWords;
    
    splitInput.forEach(input => {
        const code = input.slice(0,3);
        const latterString = input.slice(4);
        const splittedWords = [];
        
        switch(code){
            case 'S;V':
            case 'S;C':
            splitWords = latterString.split(/(?=[A-Z])/).map(word => word.toLowerCase());
            words.push(splitWords.join(' '));
            break;
            case 'S;M':
            splitWords = latterString.split(/(?=[A-Z])/).map(word => word.toLowerCase());
            splitWords[splitWords.length -1] = splitWords[splitWords.length -1].slice(0,-2);
            words.push(splitWords.join(' '));
            break;
            case 'C;V':
            combineWords = latterString.split(' ').map(word => word[0].toUpperCase() + word.slice(1));
            combineWords[0] = combineWords[0][0].toLowerCase() + combineWords[0].slice(1);
            words.push(combineWords.join(''));
            break;
            case 'C;C':
            combineWords = latterString.split(' ').map(word => word[0].toUpperCase() + word.slice(1));
            words.push(combineWords.join(''));
            break;
            case 'C;M':
            combineWords = latterString.split(' ').map(word => word[0].toUpperCase() + word.slice(1));
            combineWords[0] = combineWords[0][0].toLowerCase() + combineWords[0].slice(1);
            words.push(combineWords.join('')+ '()');
            break;
        }
    })
    
    formattedWords = words.join('\n');
    console.log(formattedWords);

    Here is my c# attempt, feel free to provide feedback, use or comment.

    using System.Text.RegularExpressions;
