Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums. You must write an algorithm with O(log n) runtime complexity.

WebSuggest Edit. Ninja has been given an array/list ‘ARR’ of unknown size and an element ‘TARGET.’. The ‘ARR’ is sorted in ascending order and all the elements of the ‘ARR’ are different. However, the size of the array is unknown to you. So Ninja can only access the 'ARR' using an interface ‘readValueAtIndex’.
WebI am not professional, but you can try use indexing. You can first create a numpy array of zeros for example: my_array = np.zeros (7) And then, you can use index to change the zero to some numbers you want. In your case, you can change 0,0,0,0,0,0,0 to 0,2,0,0,1,1,3. my_array [1] += 2 my_array [4] += 1 my_array [5] += 1 my_array [6] += 3 print ... harley fatboy lowering kitWebFind an element in an infinite length sorted array. ...
