would you mind to provide language Julia as well?

Is there a reason why Pypy is not available?

I am able to pass 21/31 testcases, using priority_queue. Rest are getting timeout. Any other option to make it more optimize?

so so easy

how can we write a prefix code of 6 as: 0000,0001,001,01,10,11

and for 9 as: 000,001,010,011,100,101,110,1110,1111 which are given in program
