Nice emoction btw XD

Say "sorry for my poor English" if you think you are not flawless ⊙﹏⊙

Please don't. It serves no purpose so it's just a few seconds wasted for every reader.

:pray: :sorz:

Thank you for these valuable tips, I hope to see beautiful blogs from now on.

As a sole member of soroush fan club I request people to start a orz chain.

Important thing IMO are some very simple punctuation rules.

• There is no space before any of the following characters: ., ,, ?, !, :.
• Sentences start with a capital letter and end with ., ?, ! or ....
• Multiple question marks or exclamation points should only be used on rare occasions.
• Don't use things like "u" for "you".

So often I see messages like

hello ?? can u help me with this problem . i got re!!!!

while the following would already be so much better:

Hello. Can you help me with this problem? I got RE.

I was taught those in first grade. They are basically the same in every language that writes in Latin or Cyrillic script. And even if your native language uses some other script and you have not "formally" learned English, it still isn't hard to emulate what the other people are doing. And even if you can't, there are so few of those rules and they are so simple.

Basically it baffles me how so many people ignore those rules.

It is also important to make sure that your blog is new.

so that you won't end up asking for a solution of a task with an editorial like this.

Use proper code formatting instead of pasting it directly in the textbox, or provide a clickable link to the submission (use ideone if the code is not a solution to a problem). Explain what your code does (or add brief comments), use proper variable naming, spacing and indentation if possible.

I don't know why I write this, but, in my opinion, one really important thing is to correctly format your code and use spoilers. I saw a bunch of blogs and comments where people just copy their submission, paste it through ctrl+v and submit their comment thinking this is a good formatted and readable thing. Come on, guys, there are so many things to format your code correctly in the standard codeforces editor.

Use spoilers when you want to ask some help with your code, I don't really know if someone really likes to scroll a comment which takes the whole page in 1920x1080 resolution. Also, copy-pasting the code without defining correct html-rules which determine if it's really a code is a disaster.

Examples:

int t;
cin >> t;
while (t--) {
    int n;
    long long s;
    cin >> n >> s;
    w = cnt = vector<int>(n - 1);
    g = vector<vector<pair<int, int>>>(n);
    for (int i = 0; i < n - 1; ++i) {
       int x, y;
       cin >> x >> y >> w[i];
       --x, --y;
       g[x].push_back({y, i});
       g[y].push_back({x, i});
    }
    dfs(0);
    set<pair<long long, int>> st;
    long long cur = 0;
    for (int i = 0; i < n - 1; ++i) {
       st.insert({getdiff(i), i});
       cur += w[i] * 1ll * cnt[i];
    }
    cerr << cur << endl;
    int ans = 0;
    while (cur > s) {
       int id = st.rbegin()->second;
       st.erase(prev(st.end()));
       cur -= getdiff(id);
       w[id] /= 2;
       st.insert({getdiff(id), id});
       ++ans;
    }
    cout << ans << endl;
}

return 0;

Good formatting, yes? I don't think so. And now goes good one.

#include <bits/stdc++.h>

using namespace std;

vector<int> w, cnt;
vector<vector<pair<int, int>>> g;

long long getdiff(int i) {
	return w[i] * 1ll * cnt[i] - (w[i] / 2) * 1ll * cnt[i];
}

void dfs(int v, int p = -1) {
	if (g[v].size() == 1) cnt[p] = 1;
	for (auto [to, id] : g[v]) {
		if (id == p) continue;
		dfs(to, id);
		if (p != -1) cnt[p] += cnt[id];
	}
}

int main() {
#ifdef _DEBUG
	freopen("input.txt", "r", stdin);
//	freopen("output.txt", "w", stdout);
#endif
	
	int t;
	cin >> t;
	while (t--) {
		int n;
		long long s;
		cin >> n >> s;
		w = cnt = vector<int>(n - 1);
		g = vector<vector<pair<int, int>>>(n);
		for (int i = 0; i < n - 1; ++i) {
			int x, y;
			cin >> x >> y >> w[i];
			--x, --y;
			g[x].push_back({y, i});
			g[y].push_back({x, i});
		}
		dfs(0);
		set<pair<long long, int>> st;
		long long cur = 0;
		for (int i = 0; i < n - 1; ++i) {
			st.insert({getdiff(i), i});
			cur += w[i] * 1ll * cnt[i];
		}
		cerr << cur << endl;
		int ans = 0;
		while (cur > s) {
			int id = st.rbegin()->second;
			st.erase(prev(st.end()));
			cur -= getdiff(id);
			w[id] /= 2;
			st.insert({getdiff(id), id});
			++ans;
		}
		cout << ans << endl;
	}
	
	return 0;
}

And even more, you can use inline code if you want to highlight some lines of your code separately. Like this: "Oh no, I had overflow in this line: cur += w[i] * 1ll * cnt[i]; and when I fixed that I got accepted!"

Length is also a factor. Blogs like this need a bit more explanations or sth in does bounds ...

They just don't feel right.

Why am I the example for being toxic xD
