#SDESheetChallenge @striver_79 @takeUforward_ a lil lil late due to fever but here i am so in today's episode of sde sheet s1 e14 1. max ones whenever u find a problem related to subarray pray to sliding window god since it was a pretty straightforward one i dint think of the brute for or O(n^2) 2 remove dublicates using a hashset is the first instinct more like muscle memory but when we optimise it since it is sorted it is easy to do using two pointers 3.

Day 4/40 Today Solved the problem of sliding window . 1) sliding window maximum 2) Subarray with k distinct integers @anjali1kumari

The N036L uses a Quad radiator element subarray with an ultra-wideband 4-channel L-band (1–1.5 GHz) transmit/receive module with output of 200 W per channel.

For a subarray to be valid: ✅ All elements can have the same frequency OR ✅ Frequencies must form exactly two groups: • One group with frequency f • Another with frequency 2f This frequency-based observation was the key to solving the problem.

💡 Q2 was interesting. My approach: • Enumerate all subarrays • Maintain frequency of each element • Track how many numbers have a given frequency • Keep track of the maximum frequency seen so far This allowed efficient validation of each subarray.

Bro asked me to find a "balanced" subarray… my life isn't even balanced 💀 LeetCode 3960 - Frequency Balance Subarray just dropped in Weekly Contest 506, basically every element has to show up either f or 2f times. sounds simple until you actually try it 😭

📚 DSA Day 2/30 Solved: Subarray Product Less Than K ✅ Leetcode #713 💡 Pattern Used: Sliding Window ⏱️ Time Complexity: O(n) 📦 Space Complexity: O(1) Another great problem to strengthen Sliding Window concepts. #LeetCode #DSA #SlidingWindow #SDESheetChallenge

209. Minimum Size Subarray Sum

Maine freq map incrementally maintain kiya tha instead of har subarray ke liye dobara calculate karne ke

Solved it last month, but forgot how to solve now. I think the trick was to find the subarray with lowest sum then subtract it from total sum??

Hit it with Kadane’s. Any max subarray is Kadane’s, then just start picking apart the invariant from there.

Day 8 – #SDESheetChallenge ✅ 📚 Topic: Arrays - IV ✅ DAY - 8 Completed!! ✔️ Largest Subarray with K sum ✔️ Count subarrays with given xor K ✔️Longest Substring Without Repeating Characters @takeUforward_ #StriversSheet #DSA #Arrays #ProblemSolving #45DaysOfCode #takeUforward

in last 2 days,i only manage to solve problems on queue like Circular tour,K Queue in Array(where i revised k stack in array problem to solve this question) and Sum of min & max elements of all subarray of size K. time to move on binary and BST.

it's literally either minimum subarray or you have to know monotonic queue, yeah, sure buddy, great fucking problem, shows your inteligence level perfectly... you just have to know one of the above

how the fuck was I supposed to know you need to take a mininum subarray..... I didn't fucking know what minimum subarray is bro FUCK

📚 DSA Day 1/30 (question 2) Solved: Fruit Into Baskets 💡Concept: Sliding Window Find the longest subarray containing at most 2 distinct elements ⏱️ Time Complexity: O(n) 📦 Space Complexity: O(1) LeetCode #904 #LeetCode #DSA #CodingInterview #Programming #SoftwareEngineer
