If the array is unsorted, the complexity is O(n) for the worst case. Otherwise O(log n) using binary search.

What is the time complexity of accessing an element of an N dimensional array?

The time complexity of the sequential search algorithm is?

O(N) where N is the number of elements in the array you are searching.So it has linear complexity.


If array is full how you apply linear search?

An array in C is structured so that it has no particular size; you have to know ahead of time what the dimensions are.So, a linear search means that you go from the first element to the last, either finding the element in the table, or going to the very last element and not finding it.Arrays in C can be zero-terminated, in which case you get the element that does not have a value, and that indicates the value you are searching for is not there.If the array is not zero terminated then you can calculate the dimension of the array, or apply the sizeof operator times the size of the first element to determine the length of the search.


How are arrays processed?

Usually one element at a time. If you want to process all elements of an array, you write a loop.Usually one element at a time.

How do you select pivot in quick sort?

quick sort has a best case time complexity of O(nlogn) and worst case time complexity of 0(n^2). the best case occurs when the pivot element choosen as the center or close to the center element of the list.the time complexity can be derived for this case as: t(n)=2*t(n/2)+n. whereas the worst case time complexity for quick sort happens when the pivot element is towards the end of the list.the time complexity for this can be derived using the recurrence eqn: t(n)=t(n-1)+n

What is the time complexity of an algorithm that uses a binary search to find an element in a sorted array in logn time?

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).


Why you need to sort an array?

Because in any type of search the element can be found at the last position of your array so time complexity of the program is increased..so if array when sorted easily finds the element within less time complexity than before..


What is the best search algorithm to use for an unsorted array?

The best search algorithm to use for an unsorted array is linear search. It involves checking each element in the array one by one until the desired element is found. This algorithm has a time complexity of O(n), where n is the number of elements in the array.


What is the time complexity of Radix Sort in terms of Big O notation?

The time complexity of Radix Sort is O(nk), where n is the number of elements in the input array and k is the number of digits in the largest element.


What is time requirement for insert operation one dimensional array state average and worst case time management?

The time-complexity of an insert operation upon an array is O(n-k), where n is the number of elements in the array (such that n>=0), and k is the position where the insertion will occur (such that k<=n). The time-complexity arises due to the need to move the last n-k elements in the array to make room for the new element. Thus inserting at or near the start of the array will take more time than inserting at or near the end of the array. Inserting at the end of an array is a constant-time operation, O(1). However, all of this presumes that the array has one or more unused elements at the end of the array to allow for expansion. If the array is full (no unused elements), the entire array must be re-allocated. For optimal performance, implementations will typically grow an array by increasing the allocation by 50% - 100%, thus time-complexity is said to be amortized rather than finite due to the occasional need to re-allocate. Note that the number of dimensions is immaterial since all arrays are intrinsically one-dimensional. That is; a two-dimensional array is nothing more than a one-dimensional array where every element is itself a one-dimensional array. The length of each element will affect the actual time taken to complete an insertion, however it does not affect the time-complexity.


What is the best and worst case time complexity of the Bubble Sort algorithm?

The best-case time complexity of the Bubble Sort algorithm is O(n), where n is the number of elements in the array. This occurs when the array is already sorted. The worst-case time complexity is O(n2), which happens when the array is sorted in reverse order.


What is the time complexity of searching a binary search tree?
