Understanding some techy terms/concepts

  • Memoization – I give you 2 candies for breakfast, you have 2 candies. 3 candies after lunch, now you have (3+2=5) 5 candies. After dinner I give you 1 candy, Ho w many candies do you have at the end of the day?(assuming you haven’t eaten any :-P) You have (5+1=6) 6 candies at the end of the day. In short, what are you doing here? You are using the count of previous candies and adding the current count to it. Rather than, counting all over from the beginning. This concept is used in Dynamic Programming, remember things to save time later.
