Your Name (Optional)

Q1 Beginner 1 pts

According to the video, what are the two major categories that coding interview patterns are split into? Video Reference:
"these patterns are split into the two major categories of leak code problems linear which work with ..."

Timestamp: 0:15

Linear and Nonlinear Arrays and Strings Trees and Graphs Pointers and Windows

Q2 Intermediate 2 pts

What specific time complexity improvement does the two-pointer pattern offer compared to the brute force approach? Video Reference:
"instead of the Brute Force approach where you might check every combination of elements which could ..."

Timestamp: 0:45

From O(n^2) to O(n) From O(n) to O(log n) From O(n^3) to O(n^2) From O(log n) to O(1)

Q3 Advanced 3 pts

The video explains that binary search can be used on which type of function beyond just sorted numerical lists? Video Reference:
"what makes binary search incredibly powerful is it can be used on any list where there is a monotoni..."

Timestamp: 3:00

Monotonic functions Polynomial functions Logarithmic functions Exponential functions

Q4 Intermediate 2 pts

According to the video, what is the key difference between processing trees versus graphs? Video Reference:
"the only difference between the two is that for a graph that could have Cycles you need some visited..."

Timestamp: 4:00

Graphs need a visited set to track nodes Trees are always binary Graphs are always directed Trees have more nodes

Q5 Beginner 1 pts

What specific data structure does BFS use to keep track of visited nodes? Video Reference:
"BFS uses a que a data structure that works like a line first in first out..."

Timestamp: 4:30

Queue (first in first out) Stack Array Hash table

Q6 Intermediate 2 pts

True or False: According to the video, the sliding window pattern is completely different from the two-pointer pattern. Video Reference:
"the sliding window pattern is an extension of the two-pointer pattern but with a more focused purpos..."

Timestamp: 2:00

True

False

Q7 Intermediate 2 pts

What is the time complexity that binary search achieves, according to the video? Video Reference:
"this is an efficient algorithm because it allows us to find our Target in logarithmic time ol log n ..."

Timestamp: 2:30

O(log n) O(n) O(n^2) O(1)

Q8 Intermediate 2 pts

How does the fast and slow pointer technique specifically work in the two-pointer pattern? Video Reference:
"the slow pointer moves one step at a time while the fast pointer moves two steps..."

Timestamp: 1:30

Slow moves one step, fast moves two steps Both move one step Both move two steps Slow moves two steps, fast moves one step
