?? Day 31 of my GFG 160 DSA Course Journey! ?? Today's challenge: Find a Peak Element. ?? I solved this using an optimized binary search approach: ? Compared mid with its neighbors to decide the search direction. ? Moved right if arr[mid] < arr[mid+1] (peak lies on the slope). ? Otherwise, moved left to explore a possible peak or stop at mid. ? Handled edge cases like single-element arrays and peaks at boundaries. ?? Key Takeaways: ? Time Complexity: O(log n) ? Space Complexity: O(1) ? Applications: Signal processing, stock analysis, and optimization problems. Feeling great about solving this with an efficient approach! It's amazing to see how binary search can solve diverse problems. ?? #gfg160 #geekstreak2024 #GeeksForGeeks #DSA #Day31 #BinarySearch #PeakElement #EfficientAlgorithms #KeepCoding #CodingJourney GeeksforGeeks
