Back to the drawing board again, it seems. The effort into this endeavour is huge, but the payoff seems distant.

1. JS Quiz

2. Behaviour

• MON - practiced 3
• THU - done 3

3. Leetcode

• MON - Daily question
• TUE - Daily question. Medium, sweep-line prefix sum.
• WED - Set Matrix Zeroes. Medium Matrix question. O(M*N) time. O(M+N) space achieved, didn't figure the O(1) space solution... though it seemed a bit extreme.
• THU - Zero Array Transformation III. Heap + Prefix Sum, it's too difficult!
• SAT - easy question
• SUN - medium Palindrome Longest Palindrome by Concatenating Two Letter Words

4. JS Coding

5. System Design

• TUE - analyse the existing pipeline's most recent 30 errors
