Once upon a time there were the 3 little pigs

each of them used to send a letter to his brothers every day to inform them of their movements. But one bad day the bad wolf discovered how to find them all, just read the messages that the postman racapitava to the post box. risk the way that day, the most intelligent of pigs then one day he decided to make a program to his brothers to be able to encode their messages on the track, the thing was appreciated by the brothers who wrote the mail from that band. purtorppo also this time the wolf discovered that the messages were pure white and having an ASCII table it was easy for him to decode. at this point the intellect little pig asks you to create a software for him and his brothers the pig tells you that it will give the program a string two input parameters, a random text ```stream``` and the message ```data``` the program will have to replace every bit of ```data``` of the last bit of the ```stream``` example

Input

```data : [11111111,11111111,11111111,11111111,111111111,11111111,11111111,11111111]``` ```stream : [10101010]```

Output

```return : [11111110,11111111,11111110,11111111,111111110,11111111,11111110,11111111]``` Because
