Thanks for your reply.

I find it in related programming problems mostly, I can't code it, or can't get a solution, for example the above problem, I found a complicated solution, and it requires a simple solution as mentioned. Other problem, that I can't code the problem, even If I know the solution, but I struggle with variables, maths,..etc.

Games and Puzzles, I'm good at it, but still didn't test my abilities so far.

The thing that I'm wondering at, I'm amazing at debugging, I worked on computer vision software with is 1+million lines, and I fixed a lot of bugs, and ported parts to opengles, ..etc. People tell me always you're very good at stepping through code, analyse it, and fix it.

I'm really wondering :( Please help from experienced guys, where is my problem exactly? The feedback from qualcomm really depressed me.

I'm interested.

As a developer, my 'flaw' is always doing the architecture for the most efficient approach to solving a problem too. I can get the job done in 2 or 3 different ways, but none of which would be ideal. I was told that practice makes perfect... I think 'code-review' helps here though. You try your way, then you are told how it could be improved. I'm lucky enough to have a sort of 'mentor' which helps me grow in that regard, perhaps you need to reassess the way you approach code review sessions?
