Striver DP Series : Dynamic Programming Problems

Striver DP Series : Dynamic Programming Problems Dynamic Programming can be described as storing answers to various sub-problems to be used later whenever required to solve the main problem. The two common dynamic programming approaches are: • Memoization: Known as the “top-down” dynamic programming, usually the problem is solved in the direction of the main problem to the base cases. • Tabulation: Known as the “bottom-up ” dynamic programming, usually the problem is solved in the direction of solving the base cases to the main problem. This post contains some hand-picked questions by Striver to learn or master Dynamic Programming.

Unit3 Lesson 15

I initially wrote a reply and then retracted it after looking further, so if you saw my first reply, I’m not sure it was accurate. Instead, what I think is happening here is something else. One potential issue is that immediately after firing, it checks to see if that bullet has made contact, but it is apparently not checking a 2nd time, so my guess is that “keyWentDown” only triggers for a limited time and the conditions of collision aren’t checked again when the bullet is further away from the pink alien. Another issue, though is that the bullet sprite is being created three times on lines 1, 52 & 59. Normally, sprites are created outside of the draw loop once (like in line 1) and then are updated inside the draw loop. When you create more than one sprite with the same name, the later ones are replacing sprites that already exist. GameLab lets you do that, but it can only track collisions on one at a time, so when multiples are created, not all of them will trigger a collision. Some potential things to look at to solve the problem. • See if they can create the bullet once outside the draw loop and then only update it inside the draw loop. • maybe create a variable such as “fired” that initially is set to 0. When the space is pressed, signaling the first time it is fired, the variable could change to 1. Then as long as the variable is 1, it could continuously check for the collision. This may eliminate the problem with the “keyWentDown” not allowing it to check for very l...
