But the main thing will remain unchanged – the core principles (and the parameters that we generate will change, their sequence or something else). We do not store the […]

The basic task sounds like this: build a minimal set of commands for transforming tree A into tree B. Problem: the general algorithm for constructing a set of operations required to transform one tree into another has a speed of O (n3). Cubic time complexity means that if we have a tree with a thousand […]

In fact, there is a mistake: this is a subtraction operation, and we need addition. The third character in the second line must be zero. In this case, it is […]
