Alan Turing - Google Doodle Solved

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.
