Week 9
You receive an email with the following image attached - there seems to be a message encoded within it. Can you figure it out?
Hints
Hints will be released at the start of each of the following days - e.g. the start of day 3 is 48 hours after the challenge starts
| Release Day | Hint |
|---|---|
| 2 | With a 'random'-looking image like this, the best place to start is to probably loop through and output the individual pixel's rgb values |
| 3 | You might notice the most common values are around 100 - the number 32 also seems to appear quite often |
| 4 | What are 32 and some of these other values if you find their corresponding character on an ASCII table? |
| 6 | You can try looping through each pixel and converting the r, g and b value to an ASCII character independently |
| 7 | You notice some black pixels at the end - it seems like this signifies the end of the message. The ASCII code 0 also corresponds to the null character, hence should probably be ignored |
