Here is the code for left to right. I have uploaded this problem on leetcode online judge using this approach. I find this approach much more intuitive than the standard solution which is present everywhere (calculating the largest building on the right and the left for each i ). int sum=...
I have the following code, made in C language, which reproduces the functionality of the mv (move) command from linux. The problem is that the code is very inefficient. How I can optimize or make the code more efficient without changing the structure too much? #include <limits.h> #inclu...
This macrois disabled if, at the moment of including<assert.h>, a macro with the name NDEBUG has already been defined. This allows for a coder to include as many assert calls as needed in a source code while debugging the program and then disable all of them for the production version ...
