    Python 3:

    q = int(input())

s = ''
revert = [s]

for _ in range(q):
    line = input().strip().split()
    operation = int(line[0])
    try:
        argument = line[1]
    except Exception:
        pass
        
    match operation:
        case 1:
            revert.append(s)
            s += argument
        case 2:
            revert.append(s)
            for _ in range(int(argument)):
                s = s[:-1]
        case 3:
            print(s[int(argument)-1])
        case 4:
            s = revert.pop()

    On the one hand

    The editor initially contains an empty string, .

    On the other hand, Why does your example start with inital value of S?!

    wtf

    JavaScript Solution:-

    function processData(input) {
    let currentString = '';
    let operationHistory = [];
    const operations = input.split('\n').slice(1); 
    for (let op of operations) {
        const opArr = op.split(' ');
        const type = parseInt(opArr[0]);
        if (type === 1) { 
            const strToAppend = opArr[1];
            currentString += strToAppend;
            operationHistory.push({ type: 1, value: strToAppend }); 
        } else if (type === 2) { // Delete operation
            const numToDelete = parseInt(opArr[1]);
            const deletedString = currentString.slice(-numToDelete); 
            currentString = currentString.slice(0, -numToDelete); 
            operationHistory.push({ type: 2, value: deletedString }); 
        } else if (type === 3) { // Print operation
            const index = parseInt(opArr[1]) - 1; 
            console.log(currentString[index]);

        } else if (type === 4) { 
            const lastOperation = operationHistory.pop();
            if (lastOperation.type === 1) { // Undo append
                const appendedString = lastOperation.value;
                currentString = currentString.slice(0, -appendedString.length); 
            } else if (lastOperation.type === 2) { // Undo delete
                const deletedString = lastOperation.value;
                currentString += deletedString;
            }
        }
    }
}
