Google, breaking the pragmatism of creating artistic doodles, has showed up a geeky doodle which is a gateway to Google search results for the greatest mathematician, natural code breaker Alan Mathison Turing who with his inventions laid the strong foundation for modern computing world. The " Alan Turning Doodle " which showed up on Google's home page today is a tribute to this ingenious.
I didn't care much to solve this doodle for the first couple of Google searches that I made today, but each time I opened Google's home page, it was be-knocking at me by tacitly asking to be solved. I began and it took little time to understand the problem to be solved and here it is.
Problem to be Solved
- User is expected to match the pattern displayed at the right top corner of the doodle.
- To match patterns, it is required to shift bits, either 0 or 1 which can be set explicitly.
- Each time the bits are set, doodle starts matching the modified pattern with the target pattern.
- And if the match is successful, each letter of the word "GOOGLE" is decoded, i.e., each character's color changes from gray scale to colored.
- Once all the characters of the word "Google" are decoded, Google redirects you to page displaying search results for Alan Turning
Approach
This is more of a permutation problem combined with the need to set or unset the bits appropriately.
Each time a character is decoded, the level and hence the complexity of the problem increases.
Decoding Patterns for Each Character
G = 01011
O = 00011
O = 00011
G = 01011
L = 01001
E = 10000
And Here is How I Did It
Though I could capture most, but few screenshots are missed.

It took a little time for me to solve, but it was worth it.
