Python

try:
    print(int(input()))
except ValueError:
    print('Bad String')

python solution first remove if name == 'main': make sure the indentation write the following code S = input() result = '' try: S = int(S) result = S except Exception as e: result = 'Bad String' finally: print(result)

read the series for the answer

c++

int main()
{
    string S;
    getline(cin, S);
    try{
        cout<<stoi(S);
    }
    catch(exception e){
        cout<<"Bad String";
    }
    return 0;
}

`if name == 'main': S = input()

try:
    print(f'{int(S)}')
except ValueError as ve:
    print(f'Bad String')`
