hello everyone

I'm Assassin.MTS from Iraq

I'm a 25 years old Programmer, and I love all kind of Puzzle/Riddles and it helped me alot in my work

I hope that I won't be annoying to anyone of you, and I hope to spend a good time with all of you solving and putting puzzles

Lastly ...sorry for my bad English

[With Flying Colors]

this is my first Post in the forum

I thought of first trial in a period of 1 and 0 like 10101010101010101010101010 and each time reverse the order of 2bits starting from the beginning if the difference between the previous answer and the last one is +2 that mean those 2bit become in a correct order... if it is -2 the 2bit was in correct order before the reverse... that give us 14 trials... but if it is 0 that mean the 2bit are of the same color... and that send me back to 27 trials... Ooops

I don't find a good answer... but I thing there is something right in this way
