Sometimes things won’t go as you’ve planned before.

yewwwws ! it's early morning though ! i usually got up early hehe

DAY-10 : #SDESheetChallenge

1. Nth node removing was literally not so tough
2. Adding two number is easy if you know when it's string
3. this was crazy ( i saw solution , crazy dude)

#DATASTRUCTURES #ALGORITHM

[Urvish Babariya @_Urvishbabariya]

i'd slept whole day today! was tired stilll consistent...

DAY-9 : #SDEsheetChallenge :)

Fav topic when yk how to move pointer, tbh i was very bad at LL lol, but when it comes to POTD. i started learning and yes i get intution now not optimal but still okayyyyyyy

#DSA #ALGO<3

@striver_79 @takeUforward_ Always loved your content @striver_79!! ❤️ Last sem I had DBMS and honestly wondered how I'd survive since the instructor just read from slides. Your SQL playlist was a lifesaver! This sem I have CN, so another benefit Please do OS ASAP!

[Urvish Babariya @_Urvishbabariya]

<3 another dayyy !! Consistent

day 8 of #SDESheetChallenge </>

Sliding window tbh :
1st : maintain map,for longest don't update further.
2nd: count subarrays with k xor.
3rd: without repeation this way key : so if any time freq>1 ele is found slide window

#DATASTRUCTURE #ALGO

[Urvish Babariya @_Urvishbabariya]

Yes another day !!! Consistent !!

🗓️ Day 7 – #SDESheetChallenge

1. 2 sum : we need to return pair so using map only by returning index
2. 4 sum : good observation from quadractic TC to o(n^3).
3. Consecutive sequence : checking whether previous element exist or not is good tbh.

[Urvish Babariya @_Urvishbabariya]

Did other 3 problem :

Day 6 – #SDESheetChallenge

1: Majority Element-II : using candidate twice variables
2. Grid unique paths : using Mathematical formula (combination)
3. Reverse Pairs: using divide and conquere

#DSALGO #OPTIMAL @takeUforward_ #visualstomorrow

[Urvish Babariya @_Urvishbabariya]

Did another 3 problems really good

🗓️ Day 5 – #SDESheetChallenge

1: Search in 2D matrix : using binary search
2: pow(x,n) : recurrence relation of odd and even case
3: Majority element I: using candidate voting

:) see you tomorrow !! <3 #DSALGO

[Urvish Babariya @_Urvishbabariya]

Did another 3 array. today it felt bit heavy.

🗓️ Day 4 – #SDESheetChallenge

1. Duplicate numbers : using slow and fast pointer. good observation.

2. repeating and missing : using map and other mathematical formula

3. inversions : using merge sort , divide and conqure

#DSALGO

[Urvish Babariya @_Urvishbabariya]

Yes, another 3 array med @takeUforward_
Day-3 #SDESheetChallenge

1. Rotate matrix by 90 deg : using swap element and reversing rows
2. Merge intervals : by tracking last inserted element, check condition and work accordingly
3.Merge array : track largest element and pointer.

[Urvish Babariya @_Urvishbabariya]

Day 2 – #SDESheetChallenge
Did another 3 array problem!
1) Maximum subarray sum : using Kadane's algo ( maintaining running sum)
2) Sort 0,1,2's : using three pointer approach ( that's very nice reducing from O(nlogn)->o(n).
3)stock buy and sell : keep track of minimum
visuals :-

#DAY1
Did 3 array problems.
1. Set-Matrix-Zero
2. Pascal's Triangle
3. Next permutations
Optimal that i thought is : 1. Maintain two array for row and column marking
2. Combinations ( using this method tc reduces)
3. STL (*next_permutation)

#SDESheetChallenge
#DSA #algo

[Urvish Babariya @_Urvishbabariya]

Staying consistent is literally tough, let we kick our journey for this another challange started by @takeUforward_ . which is starting from tomorrow onwards. but " kal se bhala aaj " , let we push. what i did is Sliding window. striver have explained it well * #SDESheetChallenge

[Urvish Babariya @_Urvishbabariya]
