Does switch statement determines appropriate case statement in same execution time for either of possible input values? Does it compare input value with case blocks and jumps to appropriate case when upon finding the value that it was looking for?

Consider example below. Does switch statement execute in same time for input = 1 or input = 256 or does it execute slower for latter value?

int output, input = 256;
    switch( input )
    {   
        case 1:
            output = 1;
            break;
        case 2:
            output = 2;
            break;
        case 4:
            output = 3;
            break;
        case 8:
            output = 4;
            break;
        case 16:
            output = 5;
            break;
        case 32:
            output = 6;
            break;
        case 64:
            output = 7;
            break;
        case 128:
            output = 8;
            break;
        case 256:
            output = 9;
            break;
        default:
            output = 0;
            break;
    }
