    Simple Javascript Solution: 

    function strangeCounter(t) {
    let a = 3;
    let x = 1;
    let y = 3;

    while (y < t) {
        a = a * 2;
        x = y + 1;
        y = x + (a - 1);
    }

    return (a - (t-x))
}

                maxSize*=2;
        }
        return (maxSize/2)-((maxSize/2)-((count-t)+1));

    start_value=3
    ending_value =3
    while ending_value <t:
        start_value *=2
        ending_value +=start_value
    return ending_value-t+1

    Simple code:

    def strangeCounter(t):
    start_value = 3
    while  start_value - 2 <= t:
        start_value *= 2
    return start_value - 2 - t
