O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
A linear search is called a sequential search because a sequential search takes linear time and therefore has a worst-case time-complexity of O(n) for a data sequence of n elements. Although there are more efficient search algorithms than linear search, not all data containers are ideally suited to them. For example, although a binary search can be performed in quadratic time (O(log n)) when the data container is in sorted order, we can only achieve maximum efficiency when the data container also supports constant-time random-access. Arrays and vectors do support constant-time random-access, but if the container is not sorted then we must resort to the less-efficient linear search. Linked lists do not support constant-time random-access thus a linear search would be more efficient even if the list were in sorted order.
If the array is unsorted, the complexity is O(n) for the worst case. Otherwise O(log n) using binary search.
O(h)
time complexity is 2^57..and space complexity is 2^(n+1).
The time complexity of heap search is O(log n), where n is the number of elements in the heap. This means that the search time complexity of a heap search operation is logarithmic in the number of elements in the heap.
The time complexity of a ternary search algorithm is O(log3 n), where n is the number of elements in the array being searched.
The time complexity of searching a binary search tree is O(log n), where n is the number of nodes in the tree.
The time complexity of a binary search algorithm is O(log n), where n is the number of elements in the sorted array being searched.
The time complexity for finding an element in a binary search tree is O(log n), where n is the number of nodes in the tree.
The time complexity of an algorithm that uses binary search to find an element in a sorted array in logn time is O(log n).
O(N) where N is the number of elements in the array you are searching.So it has linear complexity.
The time complexity of a binary search algorithm in computer science is O(log n), where n is the number of elements in the sorted array being searched.
The time complexity of an algorithm that uses a binary search on a sorted array is O(log n), where n is the size of the input array.

The time complexity of operations in a hashset data structure is typically O(1) for insertion, deletion, and search operations. This means that these operations have constant time complexity, regardless of the size of the hashset.
