I find your tutorial for segment trees very useful but I have a little suggestion. If you post some problems related to that topic in the description section then please also post the link of the solution with the same piece of code you have taught in the description section also.

I am telling this because I'm facing problem in implementing segment trees n I'm sure lots of people would be facing the same.

Everyone will agree that segment trees are not cakewalk to implement when you are an utter beginner. It's a humble request please post the link of the solution for the problem you've given with the piece of code you've taught
