Day 38 of DSA (from zero)
Today i started cpp STL
Today i start with vectors
Just take basic introduction
ie what is vector,
it is very similar to Array.
Strength > speed
Still learning...

Day 37 of DSA (from zero)
No new topic today. Day 3
Just revision.
Arrays:
1D → basics & problems
2D → matrix, diagonal, spiral
Strength > speed
Revisiting made concepts clearer

Yesterday it confused me.
Today it clicked.
Spiral → top → right → bottom → left
Layer by layer
Now it finally makes sense
Next: diagonal traversal
New pattern, new thinking
Day 35 tomorrow

Day 33 of DSA (from zero)
This one messed with my brain.
2D arrays:
Diagonal sum → odd/even cases
Transpose → swap rows & columns
Spiral → layer by layer
Spiral was confusing at first
Still figuring it out
Day 34 tomorrow

Small tools. Big impact.
fill() → initialize array in one line
No loops needed
Pairs → store 2 values
Triplets → group 3 values
Now I see how data is grouped smartly

More loops ≠ more confusion.
They build combinations.
All pairs → every combo
Pair sum → target match
Triplet sum → 3 elements
Nested loops = logic builder
Triplets were tricky… but fun
Day 29 tomorrow

Day 25 of DSA (from zero)
This problem didn’t let me win today.
Find duplicate in array
Spent 1 hour… still stuck
Tried multiple approaches
Nothing worked yet
But I didn’t quit
Problem solving isn’t always smooth
Day 26 tomorrow

Day 26 of DSA (from zero)
Solved my previously stuck problem today
Find unique → used XOR trick
a ^ a = 0, a ^ 0 = a
Also worked on sorting 0s and 1s
Goal → move all 0s before 1s
XOR felt simple yet powerful
Still exploring better logic for sorting

Brute force → smart search.
Min, Max, Sum → basic array logic
Then I saw this:
Binary Search → finds in sorted array fast
Way better than linear search
This felt like a big upgrade 🧠

Same array. Different behavior.
int arr[10]; → garbage values
int arr[10] = {}; → all 0
Indexing starts from 0
Arrays act like reference when passed
Now it feels more practical
Day 24 tomorrow

Day 22 of DSA (from zero)
This feels like real DSA now.
Arrays = data stored together in memory
Index → access elements (0-based)
Stack → may have garbage values
Heap → default initialized
Now I can actually visualize memory

This bit trick felt like magic.
Power of 2 → n & (n-1) == 0
Prime → divisibility logic
Factorial → simple multiplication
Bitwise = smart
Prime = thinking
Slowly improving

Simple problems... until edge cases appear
Reverse → rebuild digits
Integer → handle +, -, overflow
Palindrome → same forward& backward
Out-of-range values = real challenge
Now exploring
Can a number be 2^x?
Getting more interesting
#learningDSA
Day 19 of DSA (from zero)
Easy logic can still fail.
Reverse number → rebuild digits
Reverse integer → handle +, -, 0
The real challenge?
Edge cases.
Out-of-range values broke my logic
That’s where things got interesting
