Q: Linear and Binary Search Algorithms GCSE

Which statement below best describes a Linear Search carried out on a sorted array?

Which statement below best describes a Binary Search being carried out on a sorted array?

Consider the array: arr=[4,6,7,11,10,12,15].
Why will a binary search fail to find the number 10?

Consider the data set “cat”, “dog”, “gerbil”, “hamster”, “rabbit”. How many steps will be required to find the item “rabbit”, when using a ‘linear search’ algorithm? (if any non-integer values are calculated as part of the algorithm, the value will be rounded up to the nearest integer).
