WebRecursive Binary Search Implementation: Infinite Loop I implemented a Recursive Binary in C# (similar to the Java implementation). I end up with an infinite loop if I use just > rather than >= on the section below when the target value is not in the array. Infinite loop in binary search. I am trying to implement binary search with the following function: def buggy_binary_search (input, key): low = 0 high = len (input)-1 mid = (low + high)/2 while low <= high: if input [mid] == key: return mid if input [mid] > key: high = mid - 1 else: low = mid return -1.

WebIn the case of Binary Search, its time complexity is “ O (log2n) “, which means that if we double the size of the input list, the algorithm will perform just one extra iteration. Similarly, if the input size is multiplied by a thousand, then the loop will just have to run 10 more times.

WebFor binary search, the sticking point is what to return when the item we are searching for is not in the array. We could return a "sum type". In C, that's known as a "union". In C++ and Java, that's implemented as a class with 2 derived classes of different types. But that's a complicated result.
