WebSep 30, 2024 · Hashing is a special searching algorithm where the time complexity of accessing a data point is O (1). Time complexity for linear search also refers to the fact that the element that has been searched live on the first memory block, which is why its complexity is O (1); it is also known as the best case complexity.
