19. Binary Search Implementation
Below is an implementation of binary search, but the implementation contains an error. What is the error?
251 def binary_search(array, target):
252
left,right = 0,len(array)-1
while left <= right:
mid = left + ((right - left) // 2)
if target == array[mid]:
253
254
255%
256
return mid
elif target < array[mid]:
left = mid + 1
257
258
259
else:
260
right = mid - 1
261
return None
Pick ONE option
Line 253 should be change to: while left < right
Lines 258 and 260 should be switched
right should be initialized to len(array) instead of len(array)-1
Nothing is incorrect
