Your solution is almost correct for solving the Test set 1
The only mistake you have made is in function *solve1()*
Because you want to represent each worker with the binary representation of
the index, i.e. from *0* to *n-1*,
you should use
*l = len(bin(n - 1).lstrip('0b'))*
to determine the number of query you need to send.
using *bin(n)* will give you length of *11* when n is *1024*
