I got this question in unit test.

This key question is from Uniform Binary Search in chapter Searching of Data Structures & Algorithms II

Best answer
Correct option is (d) Jump search starts from the index 0 even though specified index is k

Best explanation: Linear search has O(n) complexity and Binary search has O(logn) complexity, in Jump search you have to jump backwards only once, hence it is preferable if jumping backwards is costly. Jump search starts from index k (specified index) and searches for the element. It won’t start searching from index 0.
