What is the difference between sorted and unsorted?

In the unsorted list, the placement of the items depends on the order of the insert statements. In the sorted list, the items are in alphabetical order, regardless of the insert statements.

What does unsorted array mean?

The structure of an unordered array, as described above, is a collection of items where each item holds a relative position with respect to the others. Some possible unordered array operations are given below. int list[100] creates a new list that is a size of 100, and stores elements of integer data.

Why is processing a sorted array faster than an unsorted array?

In C++, it is faster to process a sorted array than an unsorted array because of branch prediction. In computer architecture, a branch prediction determines whether a conditional branch (jump) in the instruction flow of a program is likely to be taken or not.

What is the time complexity of removing at index n in an unsorted array?

It takes O(n) time to find the element you want to delete. Then in order to delete it, you must shift all elements to the right of it one space to the left. This is also O(n) so the total complexity is linear.

Is an array ordered?

Arrays are ordered collections. i have encountered situations where the order was not preserved (in other languages), therefore the question. If arrays did not have guaranteed order we would have a problem.

What is the difference between one dimensional and two dimensional array?

A one-dimensional array stores a single list of various elements having a similar data type. A two-dimensional array stores an array of various arrays, or a list of various lists, or an array of various one-dimensional arrays.

What is median of two sorted arrays?

Medians are the middle numbers, in other words, the median value is the middle observation in an ordered list.

Why does an array need to be sorted?

Binary search works by assuming the middle of the array contains the median value in the array. If it is not sorted, this assumption does not make sense, since the median can be anywhere and cutting the array in half could mean that you cut off the number you were searching for.

What are advantages of sorted arrays?

The main benefit for an array to be sorted is that it gives a high level of certainty, because we are pretty much sure that the number to be searched is either to the right or left of a randomly selected number of the array sorted in ascending order, depending whether the searched element is greater or smaller than …
