Switch multiple case statement

Question

Can someone suggest me how can I replace the below code?

How do I rewrite the code in order to avoid the repetition of the block case 3:{code block A; break;}

Answer 1

Something like this

switch(i) {
    case 1:
    case 3:  {code block A; break;}

    case 2:  {code block b; break;}

    default: {code block default; break;}
}
