Today I saw enough 😪
One CBE branch network down, another working fine like nothing happened.

Mobile banking broke after update, Play Store app missing, use 889 also not working… and the final solution was I don’t know.🤷‍♂️

At that point I chose my health and quietly walked away from the bank 😂🏃‍♂️


Product of Array Except Self

I learned that instead of multiplying everything each time, we split it into left and right products.

What I understood:

* Left = product of elements before index
* Right = product of elements after index
* Answer = left × right


My mistake I first tried brute😭 force instead of thinking in prefix/suffix way

👉 Use left and right products to solve in O(n) time.

Integer to Roman

I used a dictionary and looped from largest to smallest value. For each value, I keep adding the symbol while it fits in the number and subtracting it.

My mistake was thinking like a list and trying to index the number instead of using a greedy approach.


Drop your thoughts not reaction😬


Idea Your Opinion Needed

I’m thinking to start a small coding challenge in this channel.

💡 If someone solves a problem, I’ll give 50 Birr airtime
✔️ No AI allowed
✔️ Must explain the solution

Do you think this is a good idea and helpful?

Drop your thoughts 👇

Roman to Integer
I first used a dictionary to map each Roman symbol to its value, then I traverse the string one by one.

For each character, I get its value and try to build the total answer.

My main confusion was that I was only focusing on the current character. I didn’t realize I also need to compare it with the next character to decide whether to add or subtract.

Now I understand:

If current value < next value → subtract
Otherwise → add

The idea is to encode a list of strings into one string using
length#word

then decode it back by reading the length first and extracting each word.

My mistake was mixing the logic in decode I tried to process the word while still searching for
#

which caused errors. I learned that decoding must follow a clear order find # read length, extract word, then move forward.

PSG Vs Arsenal

Who is going to win?

Comment the score and if arsenal loses the correct predictions I will give him prize 😂😂😂


Good morning people ☺️


Do you think failure is necessary for success?


Valid Palindrome
The idea is to first normalize the string by converting it to lowercase and removing all non-alphanumeric characters, then check if it reads the same forward and backward.

My main mistake was not clearly understanding how to properly clean the string, especially removing symbols and spaces. I also initially overcomplicated it using unnecessary loops.

In the end, I learned that the most important step is preprocessing the string correctly before doing the palindrome check.
