Day 13/45 of #SDESheetChallenge
Solved Problems:
1) Rotate a LL
2) Clone a LL with random and next pointer (add each copied pointer just after its corresponding original pointer to get rid of extra space)
3) 3 Sum

For most, #SDESheetChallenge is a 45 day challenge.
For me, it's a 191 problems commitment.

I'll keep posting daily even after day 45.
191 ÷ 3 > 45

Day 11/45 of #SDESheetChallenge
Solved problems :
1) Find the intersection point of Y LL (remembered the procedure, but had to watch the proof)
2) Detect a loop in LL
3) Reverse LL in group of given size k (watched solution)

Day 6/45 #SDESheetChallenge
Solved Problems :
1) Majority Element II ( extended version of Boyer Moore voting algorithm)
2) Grid Unique Paths
3) Reverse Pairs (had to watch the solution, bit different from count inversions)

[Madhav Bansal @MadhavBuilds]

Day 5/45 of #SDESheetChallenge
Solved Problems :
1) Search in a 2D Matrix
2) Pow(x,n)
3) Majority element I (used Boyer-Moore voting algorithm for constant space solution)

Day 4/45 of #SDESheetChallenge
Tough set today😅
Solved problems:
1) Find the Duplicate Number
2) Find the repeating and missing number
(both were tricky without using extra space)
3) Inversion of array
(had to watch the solution for optimal, was a new concept)

Day 3/45 of #SDESheetChallenge @takeUforward_
Solved problems:
Rotate matrix by 90 degrees
Merge Overlapping Subintervals
Merge two sorted arrays without extra space

[Madhav Bansal @MadhavBuilds]

Day 2/45 #SDESheetChallenge @takeUforward_
Solved problems :
1) Kedane's Algorithm
2) Sort colors
3) Stock Buy and Sell

Keeping the momentum going.

[Madhav Bansal @MadhavBuilds]

Day 1/45 #SDESheetChallenge @takeUforward_
Solved 3 problems
1) Set Matrix zeroes
2) Pascal's triangle
3) Next permutation (a bit tricky when you go for an optimal approach)

[Madhav Bansal @MadhavBuilds]

Accepted! 👍

Starting the #SDESheetChallenge @takeUforward_ on June 1st and committing to stay consistent for all 45 days.

I'll be sharing my progress and learning throughout the challenge.

Day 24: Still waiting for my refund from @reliancejio. I've provided my bank statements TWICE, raised service request THRICE, and all I get in return is a chatbot which is everywhere but useless. Is this what "customer care" looks like? @JioCare #Jio
