[arujbansal1]

I made a short tutorial on answering range queries offline with Mo’s algorithm on my YouTube channel here:
Offline Range Queries with Mo’s Algorithm

I explain how to use Mo’s algorithm in general and solve the problem Codeforces - Little Elephant and Array using it in the video.

Alternative sorting order for Mo’s algorithm:

Here are some practice problems (feel free to recommend some in the comments):

• SPOJ — Range Distinct Queries
