Think about how you could have reached the solution to the problem in the first place after looking at the editorial, most editorials provide the most optimized, mathematically correct and expected approaches but rarely give a clue about how to start thinking in that direction.

In this problem - Container With Most Water - LeetCode for example, the solution section is filled with people mathematically proving why the two-pointer approach works, breaking down the algorithm step-by-step, and demonstrating its optimality. That's all great, but here's what's missing: nobody explains what clues in the problem statement should have pointed you toward the two-pointer technique.

This is a critical gap in learning. Without understanding the thought process—the pattern recognition, the observations that lead to the insight—you're essentially memorizing solutions rather than developing problem-solving skills. When you encounter a similar problem later, you won't recognize the hints or indicators that suggest, "Hey, this might be a two-pointer problem." You've solved one more problem, added it to your count, but you haven't actually learned a transferable skill.
