  • Python bin() and int(num, 2) (for base 2) to convert between binary numbers (represented as strings) and integer datatypes.
  • f'{n:032b}’ will format n (an integer) as a 32digit binary number with padded zeros.
  • Coronavirus is affecting the markets.
  • Talked with Citadel about next steps. Scope of influence ; room to impact. This really is my most important comparator moving forward. More than title/salary/sector.
  • DS&A:
  • https://leetcode.com/problems/reverse-bits/. Binary work.
  • https://leetcode.com/problems/number-of-1-bits/. Same.
  • https://leetcode.com/problems/number-of-islands. DFS through each known land cell, count groupings and return.
  • https://leetcode.com/problems/happy-number/. Try something in a loop, detect cycle by keeping tracking of seen numbers in a set.
  • https://leetcode.com/problems/count-primes/. Sieve of eratosthenes. Prime numbers up to n. Zero 0 and 1. Then zero out all multiples of every number from 2 to sqrt(n).
  • Between all platforms (leetcode, hackerrank, geeksforgeeks, interviews themselves) I’ve done ~200 practice problems.
  • FB coding interview II.
  • Graded on 4 aspects of the DS&A questions. Problem solving. Communication. Converting algorithms and data structures to executable code. Validation (testing).
  • Notes all in gdrive. 2 coding questions. Did both. I like that they were formatted in real-world applications, with a quick discussion before diving into the algorithm.
  • I continue to be impressed with facebook’s process, in direct relation to its closest interview cousin Google. The focus is multiheaded, from intuition to coding to behavior. Google is much more what, Facebook is much more what how why when where who.
  • Cut and wrapped 32 homemade pumpkin peanut butter bars for the next month.
  • Paid the last rent (maybe last rent ever?) for feb in hermosa. Gave Sherisse formal 30d notice.
  • If a bonus is paid as a supplemental wage, it’s taxed at the flat rate of 25%. If it’s added onto the year-end paycheck, it’s additional income and is taxed at whatever aggregate tax bracket that income is within (which is obviously worse).
