WebAug 4, 2024 · A linear search is the most simple search algorithm. Each data item is searched in order from the first value to the last as if they were all laid out in a line. The list does not have to be in any order before it is searched. This search is also known as a sequential search because the list is searched in a sequence from start to end. WebA binary search algorithm is an algorithm that starts in the centre of a list and finds out of the value is greater or less than the value at the mid point (or if it is the value!) The unused part of the list it then discarded and the …
