C++ Basics in One Shot - Strivers A2Z DSA Course - L1
o This is a full-fledged interview preparation website that I run on my end so if you 're
someone who has three months to like six months of time left for interviews I will definitely
ask you how to check this Strivers SD sheet. This is one of the most followed resources in the
country as of now what does this resource gives you it gives you 119 well curated problems
such that all your DS algo Concepts will be covered. You should definitely check out coding
ninjas because web development okay data Stitch algorithm foreign County there 's a link in
the description make sure you check them out I 'll be using vs code in order to code I'll be
writing my C plus plus code over here and whatever the code generates as an output will be
produced over here. In the next video we will be covering Java 1. C plus plus we can use the
hash include so hash include i o stream imagine if you want to use something like a math dot
h I 'll be talking about radical functions afterwards. C out is a function which exists under the
STD and double colon so in order to use C out you have to write STD.
o Time and Space Complexity - Strivers A2Z DSA Course
This is the continuation of Strivers A to Z DSA course slash cheat so uh if you remember in the
previous video we have covered all of these green TIG Mark things. This video will be covering the
time complexity learn Basics and then analyze the next steps. Eventually when you complete all the
steps or all the problems you will have a very very good hold on time complexity. Time complexity
can not be said as time taken because it is dependent on system it is different dependent on
configuration right so this is why that is this is the first point time taken is never equal to time taken.
Time complexity is what you call As Time complexity depending on the input if they are giving you
more input it might end up taking a certain more time so the rate at which the time increases is what
is generically referred as time complexity. Raj explains how to compute the time complexity or the
Big O of a piece of code. Raj says that in all the interviews that you're going to give or all the
examinations if you 're writing a code they will ask you to analyze the time that is when you do not
like you will not say two seconds no you will say it in terms of bigon notation.
Solve any Pattern Question - Trick Explained | 22 Patterns in 1 Shot | Strivers A2Z DSA
Course
take U forward
The scribers A to Z DSA course will teach you four steps that will help you to print any pattern in the
world. All the patterns that you will be printing will have nested Loops. The outer loop is specifically
for the lines the inner loop is for the columns. The first three steps are mandatory the fourth step is
an optional one we will solve patterns which will be requiring uh observing symmetry so let 's come
to the first pattern I 'll be explaining this in depth and then the next patterns we will be moving
faster if you look at this pattern. The fourth one is observe symmetry in case of some patterns
observe symmetry. The inner loop will be very straightforward and it will be running for J do not take
a dive okay because I is the outer loop J equal to zero J lesser than 4 J plus plus plus can I see this this
will be your inner loop. Once you have done everything for the first line you have to actually go to
the new line.
