#1

did understand how time complexity is calculated in q3

#2

hello @mansi25
pls share the question screenshot with me

#3

question is there in quiz 2 of stl challenge

#4

i have questions but they are not in order. thats why asking it from u

#5

i am not getting from where to attach pic…question is to calculate time complexity of a fun named calSum

#6

Its N^2 because vector is passed by value
So for each recursive call its copied to another vector

So for N calls vector of size N is copied
=> N^2
