Searching an unsorted array for a value and determining its space and time complexity.

• The time complexity of linear search is O(n), where n is the size of the array.

• Binary search has a time complexity of O(log n), but requires a sorted array.

• Hash tables can provide constant time complexity for search, but require additional space.

• The best search method depends on the specific use case and constraints.

• Example: Searching for a name in a list of names.

Sorting and searching algos have different space and time complexities. The best algo depends on the use case.

• Sorting algos: Bubble sort, Insertion sort, Selection sort, Merge sort, Quick sort
