binary max start pattern

 binary = readline(); // The input string.

let max = 2**binary.length

for(let i = 0; i < max; i++) {
    let rep = i.toString(2)
    while(rep.length < binary.length)
        rep = '0' + rep
    let fail = false
    for(let j = 0; j < rep.length; j++)
        if(binary[j] != '?' && rep[j] != binary[j])
            fail = true
    if(!fail)
        print(rep)
