In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again … dicks pearland

We must know the case that causes maximum number of operations to be executed. For Linear Search, the worst case happens when the element to be searched (x in the above code) is not present in the array. WebTo model our recurrence, we define a function T(N) as the maximum number of comparisons (remember, this is a worst-case analysis) to search a sorted subarray of length N. We can define the runtime of binary search using the following recurrence. (Assume floor division for N / 2 to keep the math simple.) Binary search T(N) = T(N / 2) … city and guilds maths level 3
