Nettet12. jul. 2024 · The time complexity of the above algorithm is O(n) because we’re visiting each node exactly once. The space complexity is O(log n) because, I have used recursion here. Here are some more problems that can be solved using binary search algorithm. You can practice them to understand the algorithm better: Nettet19. mar. 2024 · static int binarySearch (int [] array, int left, int right, int key) { if (left > right) { return -1; } int mid = (left + right) / 2; if (array [mid] == key) { return mid; } if (array [mid] > key) { return binarySearch (array, mid + 1, right, key); } return binarySearch (array, left, mid - 1, key); } Share Improve this answer Follow
