LeetCode Contest 466 – Q2
Minimum Operations to Transform String
Solved in contest!
Compared both strings → tracked mismatches → calculated ops based on differences
Great mix of string traversal & greedy logic!
#LeetCode #Contest #PythonDSA #DSA #DailyPractice
LeetCode 2 – Add Two Numbers
Solved: Add two numbers represented as linked lists
Traverse both lists digit by digit → keep carry
Build new list as result
O(max(m,n)) time, O(1) extra space
Classic linked list + math simulation problem!
#LeetCode #LinkedList #DSA #PythonDSA
LeetCode 160 – Intersection of Two Linked Lists
Solved: Find node where two linked lists intersect
Used two pointers → move each to other list after reaching end
They meet at intersection or null
O(n) time, O(1) space
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 148 – Sort List
Solved: Sort a linked list in O(n log n)
Used merge sort → find mid, sort halves, merge
O(n log n) time, O(1) space (linked list friendly)
Great practice for divide & conquer!
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 877 – Stone Game
Solved: Predict winner in stone game with optimal play
Mathematical insight → Alex always wins if piles > 1
No DP needed, just return True
#LeetCode #100DaysOfCode #GameTheory #DSA #PythonDSA
LeetCode 2095 – Delete the Middle Node of a Linked List
Solved: Delete the middle node in a linked list
Used slow & fast pointers to find middle
Then skipped the middle by adjusting links
O(n) time, O(1) space
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 19 – Remove Nth Node From End of List
Solved: Remove the nth node from end
Two-pointer approach → move fast n steps ahead, then move both till fast hits end
Adjust links to skip target node
O(n) time, O(1) space
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 328 – Odd Even Linked List
Solved: Group all odd-indexed nodes, then even-indexed nodes
Maintained two lists (odd & even) → connected at the end
O(n) time, O(1) space
Good practice in rearranging linked lists!
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 234 – Palindrome Linked List
Solved: Check if a linked list is a palindrome
Steps:
Find middle (slow & fast pointers)
Reverse 2nd half of list
Compare first & second half nodes
O(n) time, O(1) space
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 876 – Middle of the Linked List
Solved: Find middle node of a linked list
Used slow & fast pointers → when fast hits end, slow is at middle
O(n) time, O(1) space
Clean & elegant pointer trick!
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 142 – Linked List Cycle II
Solved: Detect cycle and return starting node
Step 1: Use Floyd’s Cycle Detection (slow & fast)
Step 2: Once they meet, move one pointer to head→ step both by 1→meet at cycle start
O(n) time, O(1) space
#LeetCode #LinkedList #DSA #PythonDSA
LeetCode 2396 – Strictly Palindromic Number
Solved: Check if n is palindromic in every base 2…n-2
Trick: No number ≥ 4 can ever be strictly palindromic → always false
Math observation > brute force!
#LeetCode #100DaysOfCode #Math #PythonDSA
LeetCode 141 – Linked List Cycle
Solved: Detect cycle in a linked list
Used Floyd’s Cycle Detection (slow & fast pointers)
If pointers meet → cycle exists
O(n) time, O(1) space
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 206 – Reverse Linked List
Solved: Reverse a singly linked list
Iterative: keep track of prev, curr, next
Re-point https://t.co/eLD2RDaAe3 → prev until null
Classic linked list must-know!
#LeetCode #100DaysOfCode #LinkedList #DSA #PythonDSA
LeetCode 237 – Delete Node in a Linked List
Solved: Delete a node (not head) in a singly linked list
Trick: Copy value from next into current node → skip next
O(1) time, O(1) space
Simple yet clever linked list manipulation!
#LeetCode #100DaysOfCode #LinkedList #PythonDSA
Haven’t posted here for a few days… but I’ve been solving daily on LeetCode
Getting back to posting solutions again from today

LeetCode Contest Update
Q1. Restore Finishing Order
Submitted in today’s contest!
Idea: Use given ranks to rebuild correct order by mapping participants back to their positions.
Efficient simulation with array/indexing.
#LeetCode #Contest #100DaysOfCode #DSA #PythonDSA
LeetCode 1283 – Find the Smallest Divisor Given a Threshold
Find the smallest divisor so that sum of [num/div]≤threshold
Used binary search on divisor range[1…max(nums)]
For each mid, compute sum
If sum-threshold:increase divisor
Else:shrink search space
#LeetCode #PythonDSA
LeetCode 1614 – Maximum Nesting Depth of Parentheses
Solved: Find max depth of nested parentheses
Traverse string, increment on '(',decrement on ')'
Track maximum depth reached
O(n) time, O(1)space
Simple yet useful stack-like logic!
#LeetCode #100DaysOfCode #PythonDSA #Strings
LeetCode 8 – String to Integer (atoi)
Solved: Convert string to 32-bit signed integer
Steps:
Ignore leading spaces
Handle sign + / -
Build number till non-digit
Clamp to integer range
Classic string parsing problem!
