can someone please explain what exactly is size which is displayed after submitting the code?

Hello Kaushik,

Cody initially used a code-size point system for solving a problem, which gave you points according to the size of the solution. That was, the smaller your solution size, the more points you got.

The solution size is calculated as follows - "Cody uses a node-count calculation to determine the solution size based on the number of nodes in the parse tree. Think of size as code length. Comments do not contribute to code size."

Also note that the scoring system was changed to fixed points system (10 points for solving a problem) some time ago.
