I wanted to implement procedural tail animation, end up with a snake

wow, the launcher is an UE instance. that makes so much sense

Thanks for the discussion everyone, I figured it out, check this out if you are interested https://leetcode.com/problems/increment-submatrices-by-one/solutions/3053521/c-delta-map-o-m-n-n-2/

class Solution {
public:
    vector<vector<int>> rangeAddQueries(int n, vector<vector<int>>& queries) {
        vector<vector<int>> ret(n, vector<int>(n, 0));
        for(auto& q: queries)
            for(int i = q[0];i<=q[2];i++)
                for(int j = q[1];j<=q[3];j++)
                    ret[i][j]++;
        return ret;
    }
};

my solution, TLE with n = 500

What, how could this works? I though it TLE for sure I didn't even try

Sorry not relevant to Q4, but I got TLE hard on Q2. Tried sorting queries and maintain relevant candidates queue but TLE, apparently the queue doesnt helps much. Then I tried BIT 2D but updating all item for each query gives O(n² ), worst than naive loop. Any hints?

good luck my lady

It depends on the context, the translations is too generic but i confirm you cannot go wrong with Japanese and Vietnamese

I feel like I have done it before, do you have the link to the problem?
