Engagement
20 posts held, back to 28 March 2024 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 7 April 2024. An engagement rate over an empty window would be a number about nothing.
Reaction mix
93 reactions across 17 posts, in 3 distinct kinds. The most used accounts for 69.9% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 65 | 69.9% | |
| ❤ | 15 | 16.1% | |
| 👌 | 13 | 14.0% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 18 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 93reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 28 March 2024 to 7 April 2024, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Here is the Step-by-Step Algorithm of Bubble Sort 1. Start with the first element of the array and compare it with the next element. 2. If the next element is smaller, swap them. 3. Move to the next element and repeat the comparison and swapping process until the end of the array. 4. Once the first pass is complete, start the second pass from the first element again and repeat the same comparison and swapping pr…

Interviewers use DP questions to assess candidates' problem-solving abilities, algorithmic thinking skills, understanding of fundamental DP principles, and coding proficiency. Candidates who can demonstrate these qualities are more likely to succeed in technical interviews. We can categorize DP problems from medium to high difficulty. * DP problems often require breaking down complex problems into simpler subproblem…

Showing the 12 most recent of 20 posts we hold for @tcctelegram. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
