#4

Hi,

Day 4 is FINALLY DONE!!!

A day when you don't learn something is a day wasted

Today's leetcode problem bought back memories & previous struggles I had with questions involving operations on strings. 

It was nice to go back (it felt like I was seeing string/substrings for first time 😅) to the fundamentals and try to  figure out how to extract a substring from a string

Spent better part of an hour just understanding how string manipulation works in python, how to extract substring, extract all combinations of substring and then count frequency of these substrings.

So that was today's learning update. 

Looking forward to learning python fundamentals by taking a more implementation heavy approach for coming days as today was more learning focused.

Learning Today

The most interesting part about today was learning about the window sliding approach.

Using that improves both Time & Space Complexity and it is way better approach than that of brute force (incase of this problem)

Key Takeaways

My understanding of strings stands on a flaky foundation and I need to go back to basics to learn them 

Figuring out how to approach problems with string is needed, as coupled with foundational knowledge weakness , irrational fear of string related questions is also present.

Learning to do

String operations : extract substring (longest,shortest,unique,etc) 

Dictionary data structure in python.

As this is just information gap, given enough time & effort, I intend to know how to approach string related questions

Looking forward to #5
