Pity card game, that's the last card of scammers. You have this picture but don't have a receipt from the hospital that operated you. You was not aware the money you paid was for one leg. Also didn't expect your savings to go into your second leg operation. Getat guy.

One of the most starred repos for learning system design. Covers: – scalability basics – load balancing, caching, databases – real interview questions + solutions If you’re targeting high-paying backend roles, this repo alone is enough to get started. github.com/donnemartin/sy…

And if you’re targeting specific companies, add these: Amazon: 146 LRU Cache 692 Top K Frequent Words 994 Rotting Oranges 863 All Nodes Distance K in Binary Tree 1152 Analyze User Website Visit Pattern Google: 23 Merge k Sorted Lists 224 Basic Calculator 772 Basic Calculator III 129 Sum Root to Leaf Numbers 358 Rearrange String k Distance Apart Meta: 560 Subarray Sum Equals K 1762 Buildings With an Ocean View 670 Maximum Swap 987 Vertical Order Traversal of a Binary Tree 1249 Minimum Remove to Make Valid Parentheses Microsoft: 139 Word Break 56 Merge Intervals 236 Lowest Common Ancestor 240 Search a 2D Matrix II 460 LFU Cache Uber: 127 Word Ladder 973 K Closest Points 297 Serialize and Deserialize Binary Tree 253 Meeting Rooms II 341 Flatten Nested List Iterator Netflix: 981 Time Based Key-Value Store 636 Exclusive Time of Functions 721 Accounts Merge 295 Find Median from Data Stream 79 Word Search --- If you do: 10 patterns x 4-6 good problems each 20-25 company-focused questions You’ll already be more prepared than most candidates who just say “I’ve done 500+ LeetCode.” Solve by pattern. Revise by template. Practice by company. That’s how you can crack DSA rounds fast.

Preparing for DSA interview, do these leetcode problems! 1. Sliding Window: 3, 76, 424, 904 2. Two Pointers: 11, 15, 167, 42 3. Binary Search: 33, 153, 875, 1011 4. Hashing + Prefix: 1, 49, 560, 128 5. Monotonic Stack: 739, 503, 84, 901 6. Heap (Top K): 215, 347, 973, 703 7. Intervals: 56, 435, 57, 252 8. BFS/DFS: 200, 994, 102, 133 9. Trees: 104, 236, 543, 124 10. DP basics: 70, 198, 322, 300 Just 2-3 per pattern, write the template from memory, then speedrun variants.
