Hi, Guys ...
Let me tell u what I did today towards my goal
if u don't my goal then check this out:https://dev.to/thedharsan/my-power-pack-goal-for-the-next-7-5-months-roadmap-2jai

NOTE: if u want to learn what I am learning I will provide the resource that u can also learn from and continue!!

1.Learned about Array Concepts in Detailed with complex problems

resouce:https://www.geeksforgeeks.org/analysis-algorithms-big-o-analysis/?ref=leftbar-rightbar

what I learned:
*Stock buy and sell the problem

*Trapping rainwater
*Maximum consecutive 1s
*largest even Odd Subarray
*Maximum circular sum subarray
*Majority element
*sliding window
*prefix sum technique

These questions mention above solved from naive to the optimized way
you can search in GFG for problems and solutions also.

link for SDE Sheet:https://docs.google.com/document/d/1SM92efk8oDl8nyVw8NHPnbGexTS9W-1gmTEYfEurLWQ/edit
And For SDE sheet Part:

1.find the Majority element (n/2) that appears in the array
2.find the Majority element (n/3) that appears in the array

See you tomorrow in post guys✌👍😎!!!

1.Learned about Time complexity

resouce:https://www.geeksforgeeks.org/analysis-algorithms-big-o-analysis/?ref=leftbar-rightbar

2.Learned about Array Data Structure:

resource:https://www.geeksforgeeks.org/array-data-structure/

what I learned:
*operations in array(insertion,deletion,..etc)
*Largest element in Array
*Second largest element in Array
*Check if the array is sorted
*Reverse an Array
*Remove Duplicates in array
*Move Zeros to end
*Left rotate array by one and by d places also
*Leaders in array
*Maximum difference Problem with order
*Frequencies in a sorted array

These questions mention above solve from naive to the optimized way

link for SDE Sheet:https://docs.google.com/document/d/1SM92efk8oDl8nyVw8NHPnbGexTS9W-1gmTEYfEurLWQ/edit
And For SDE sheet Part:

1.Sort an array of 0’s 1’s 2’s without using extra space or sorting Algorithms

2.Kadane’s Algorithm

See you tomorrow in post guys✌👍😎!!!

My Power Pack Goal for the next 7.5 months (roadmap😎👍)

Dharsan.S — Sat, 13 Feb 2021 17:34:17 +0000

4 Months(DSA) + 3.5 Months(Competitive Programming)

DSA(4 months):
For the first 3 months, I learn DSA from GFG DSA paid Course by Sandeep Jain.

Striver's SDE Sheet(180 questions) link: https://docs.google.com/document/d/1SM92efk8oDl8nyVw8NHPnbGexTS9W-1gmTEYfEurLWQ/edit

I will do 2 Problems a day for 90 days from FEB 15/2021

Note: if u are following this roadmap then take the concept from the above 180 questions

Tip for Students like me in time management:
In normal days do in (5.00 AM -> 8.30 AM) and (7 PM -> 10.30 PM)

For the next 1 Month, I will do Love Babbar Cracker Sheet(450 questions)

link for Love Babbar 450 sheet: https://drive.google.com/file/d/1FMdN_OCfOI0iAeDlqswCiC2DZzD4nPsb/view

I'm Going to do 14 questions a day for 30 days
_____________________________

CP(3.5 months):

love babbar Cp roadmap:
https://whimsical.com/codeforces-candidate-master-roadmap-by-love-babbar-CiXPPD3CnwoXPr2d8Ajx1h

I am going to follow this roadmap for Cp

And while learning Algorithms for Cp I will practice in TUF CP LIST

TUF striver Cp list: https://docs.google.com/document/d/1vShwt8yXYUOgkF53-iYAuJXWR7Yi5VSJrW2xB49o0PM/edit

Tip: In this stage, I will read 1 interview experience in GFG a day daily to refresh DSA and do Leetcode random problems

That's it guys for the goal for the next 7.5 months. if u want to follow Me and my roadmap.. Like it and Let's do it together
I will Upload Post daily which describes what I learned that day
so u can also see my progress and for my consistency!!

Hope u like it and Peace✌✌✌
