General Formatting Title

Paste this for source link, if it doesn't work, then leave it be.

Just a reminder for me, if I want to format anything.

KEY -> Used for Input variables, such as a, b, x, n

$f(x) = formulae$ -> Math formula, if needed, also used on constraints.

Each Question should consist of:

• Question

• Constraints

• Input and Output Type

• Tabs for Sample Inputs & Outputs

• Accordion for Proposed Solution

Only collects the competitions I had taken, and hopefully the solutions are correct (huh)

aka, I won't collect leetcode related codes as they are elementary.
