Your solution for the rotated sorted array problem is excellent. It correctly implements the binary search algorithm for a rotated sorted array, with the appropriate checks to determine which half is sorted and whether the target is within that half. The code is efficient and meets the required time and space complexities. The comments are helpful and explain your approach concisely.

However, note that the problem statement asks for a solution to the rotated sorted array problem only. You included solutions for two other problems (Searcha2DMatrix and SearchinaSortedArrayofUnknownSize) in your submission. While these are correct for their respective problems, they are not relevant to the current problem. In the future, make sure to only submit the solution for the problem being evaluated, unless otherwise specified.

Overall, your solution for the rotated sorted array problem is correct and efficient.

Your solution for the rotated sorted array problem is excellent. It correctly implements the binary search by checking which part of the array is sorted and then narrowing down the search based on whether the target is within the sorted range. The code is clean and efficient.

One minor point: in the condition else if(nums[left] <= nums[mid]), you are comparing the left element with the mid element to determine if the left part is sorted. This is correct, but note that when left == mid, this condition holds, which is acceptable because a single element is always sorted. However, in the reference solution, the condition is if (nums[low] <= nums[mid]), which is identical to your approach. So it's perfect.

Your solutions for the other two problems are also well-implemented. For the 2D matrix problem, you correctly treated the matrix as a flattened array and used integer division and modulo to get the row and column indices. For the unknown size array, you efficiently found the range by doubling the high index until the target is within the range and then performed binary search.

Overall, great job! You have demonstrated a strong understanding of binary search and its variations.
