Caesar Cipher shifts every character by a constant. It's easy to code if we use ASCII values.

Thanks for giving us these hard questions with easy videos to ubderstand. Hello kamiel my name is nayeem bin reza and I have just admitted to highschool and my classes hasn't started yet. From the pandemic I grew with the interest of coding , problem solving. your videos inspires me and motivates me. thanks for making these videos . THE answer tthe homework 1 is: #include using namespace std; string ceaser_cipher (string s, int k){ string s2; for ( char& c : s ){ int x = c; if ( 65
That moment he talked about using mod 26 that clicked something in my brain
Errichto, your videos are very good. CP is not only a "sport" for many of us, is also a hobby. Incredible work as always.
Making videos like this raises our level and makes us think in a different way. Please continue with such videos
This is an amazing video! Kindly make more of these since you explain it very well and I think this would be extremely helpful for everyone as well. May you be in the best of your health. Thank you.
Your videos give me peace, they are so easy to follow and i feel really comfortable. Keep up the good content!
Errichto we all miss your videos, Please help us all by uploading more frequent videos, We miss you!!🙃 Also please upload : - Beginner level algo video - Pls do consider Leetcode video - Codeforces round(Optional) Thanks
He hasn't done Codeforces in a while I thing so yeah maybe he should do a screencast of the next div 1 contest
Errichto thanks for this video and this explanation. I was running a totally different (and complex) solution to Ceasar Cipher due to a lack of knowledge about operations with characters. This was very helpful.
I love these videos. I am trying to learn C++ and trying to get in to competitive programming and this is useful. Thank you
Thank you dear Kamil! Cheers from ARG 🇦🇷
please continue this beginner series, it's very helpful
Errichto, thanks. Good clear explanation of the matter.
I think this series of videos where you teach beginners is very good
this moment is called happiness
Thank you for the great lessons
Errichto it was really interesting video. Thank a lot.
This serie Algo for Beginners, is really nice, even if you are not a begginer
Please keep doing this work. 🙏
wonderful content
Thank for existing
thx bruh from all my heart 😍
wow, you are back!!! yeah.
Thanks for sharing
Errichto looks more handsome without his specs 😂😂❣️
Thanks Errichto...for helping NOobs
Can you suggest any books or tutorial for advanced c++ for competitive programming?you can also do a tutorial
Hi, can you make a small video on matroids which are used to prove the correctness of greedy algorithms?
What happened to the weekly interview streams?
Kamil you looks really different without glasses.Good Luck brother.
Hi What data types will be used in for loop to read and encrypt a whole sentence. Thanks in advance
Hi Errichto Hi Guys I have a doubt In bit masking how do we bit mask a negative number? Like for an example if we want to find the bit mask of the vector [2, 4,-7, -9] Then how should we do it?
hey i am a beginner i was able to decode and cipher uppercase and also spaces but how do i do special characters? do special characters get stored in string datatype? then how will typecast or store them pls help i want to do it with similar logic using function calls
hi Errichto, i tried to contact you on various platforms. just asking, where are you most active ?
Erricho which tool is this for drawing? Could you please name this?
I normally use Onenote, but this time it's just Kolourpaint (which is Ubuntu version of Paint).
@@Errichto Thanks Errichto. How have you been, we see fewer streams from your end, we really miss you!
Thankyou++;
What is the name of the program that he draws in it
Can someone explain to me in the digit squared why does it have to be x*x
Errichto is the caesar ...
Hit like who wants DSA playlist by him...💜
what a good mam
Will there be a time where people can't create new problems and CP will die? I hope that doesn't happen.
First Like , First comment!
Fuck Valentine's me and the boiis only watch Kamil teaching us ASCII.
pozdrawiam, szkoda ze nie odpisales na email :)
Before RU - Ukraine War you teach people how to cipher "Attack" ? lmao !
Wait what? You are teaching people to use bits/stdc++.h and include namespace std? That's REALLY frowned upon by the major C++ community. Please teach newbies the proper way of including and scoping.
Yes, I use those. I teach algorithms, not proper C++ style. While "bits" doesn't always compile, everybody uses "using namespace std" in competitive programming. It's just so convenient. Learning computational thinking is important. When you have a job, it's easy to stop using something. Similarly, it's ok to teach basic English with sentences like "this is pen" instead of "this is a pen". (But I get your point and I don't claim that my method of teaching is superior.)
