Note: This repl.it project was my sandbox/playground while I was studying for my FAANG interviews - not all data-structures and/or algorithms are guaranteed to work. This repl.it project is like my personal notes/journal - not professionally backed or tested. I could be wrong in my implementation and some parts may not work all together.
Feel free to comment below if you want clarification on the credibility of some of the data structures shown in my practice repo.
This is the index.js page shown in the repl.it linked above. Uncomment the require statement that loads the file to the given data structure you want to tinker with then press the play/run button to re-execute the code.
/**----------------------------------------------
| Arrays
*-----------------------------------------------
|
| . Pros
| - Ordered
| - Fast lookups
| - Fast push & pop
|
| . Cons
| - Slow iserts
| - Slow deletes
| - Fixed size (when using static arrays)
|
| . Operations
| - append O(1)*
| -> may be O(n)
| -> if allocated memory block needs more space
| - lookup O(1)
| - insert O(n)
| - delete O(n)
