What is the time to sort n numbers in linear time?
Sort n numbers in range from 0 to n^2 – 1 in linear time - Searching and sorting - If we use Counting Sort, it would take O(n^2) time as the given range is of size n^2. Using any comparison based sorting like Merge Sort, Heap Sort, .. etc would take O(nLogn) time.
What is the time required to sort an array of numbers?
Sort n numbers in range from 0 to n^2 – 1 in linear time - Searching and sorting - If we use Counting Sort, it would take O(n^2) time as the given range is of size n^2. Using any comparison based sorting like Merge Sort, Heap Sort, .. etc would take O(nLogn) time. Given an array of numbers of size n.
How to sort if range is from 0 to n^3-1?
1) Subtract all numbers by 1. 2) Since the range is now 0 to n2, do counting sort twice as done in the above implementation. 3) After the elements are sorted, add 1 to all numbers to obtain the original numbers. See also C++ Programming - Rearranged to form a palindrome How to sort if range is from 0 to n^3 -1?
Is it possible to sort in less than O(nlogn) for a function?
If you consider given 750 as constant, it sorts at O (n). Comparison based sorting can't sort in less than O (nlogn), but if number of values is bounded by D, you can sort in O (D*n), or O (n) if you consider D as constant. Sure its a theorem. Any comparison algorithm is O (n log n).
Can you sort in time O n?
If you consider given 750 as constant, it sorts at O(n). Comparison based sorting can't sort in less than O(nlogn), but if number of values is bounded by D, you can sort in O(D*n), or O(n) if you consider D as constant.
Can sorting be done in O of n time?
We have now introduced several algorithms that can sort n numbers in O(n lg n) time. Merge sort and heapsort achieve this upper bound in the worst case; quicksort achieves it on average.
Can we sort an array in O n time?
Yes. If you do not have any limitations regarding space complexity then you can sort the array with o(n) time complexity.

Which sorting is the fastest?
QuicksortBut since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.
Is O 1 sorting algorithm possible?
Yes. But it only works on lists that are out of order only within the first quadrillion items. Algorithm: bubble sort the first quadrillion items. Worst case complexity: O(1).
How do you sort an array in time?
There are many ways by which the array can be sorted in ascending order, like:Selection Sort.Binary Sort.Merge Sort.Radix Sort.Insertion Sort, etc.
What is the time complexity of selection sort?
Complexity Analysis of Selection Sort Therefore, the selection sort algorithm encompasses a time complexity of O(n2) and a space complexity of O(1) because it necessitates some extra memory space for temp variable for swapping.
What is the runtime of arrays sort?
Arrays. sort has two different sorting algorithms. Quicksort, a non-stable algorithm, and Timsort, a stable algorithm. Both share a time complexity of O(n log n) , where n is the total number of items in the array.
How does n2 time sorting algorithm work?
Linear search in arrays is the best example of linear time complexity. O(n2): This denotes quadratic time. O(n2) means that the performance is directly proportional to the square of the input taken. In simple, the time taken for execution will take square times the input size.
What is the slowest sorting algorithm?
HeapSort: It is the slowest of the sorting algorithms but unlike merge and quick sort it does not require massive recursion or multiple arrays to work.
Is log n sorting possible?
This means that any sorting algorithm has a lower bound of n , and since n > log(n) , a log(n) sort is impossible.
Is sorting n log n?
Sorting the characters in a string is not necessarily O(n log n). O(n log n) is the optimal value for a comparison sort. It is also the complexity of many languages' default sort implementation. However it's certainly possible to do worse than this.
Can you sort n numbers faster than n log n?
In short, no, you can't do much better than O(n lg n), but you can do marginally better if you know something about your input.
Which sorting algorithm has the best asymptotic runtime complexity?
The worst case best run time complexity is O(nlogn) which is given by -Merge Sort and Heap Sort.
Which sorting is not in-place?
Merge-sort is an example of not-in-place sorting.
is it possible to master algorithms and data structures without being good in math?
I understand basics of math: probability, calculus, discrete math, linear algebra (all at basic level), can I master algorithms and data structures and understand advanced topics such as AI? when I tried to understand advanced topics in algorithms such as B-TREEs and graph algorithms, I always got stuck and may be it's because of me not having enough mathematical thinking abilities...
When to use Dynamic Programming?
I guess the topic says it all but still, I'll elaborate. I've been solving some coding questions for fun and there was this problem which I could solve but the solution was NOT AT ALL elegant. I looked at a solution code and was blown away when the problem was solved by dynamic programming.
K-Map pairing Algorithm
I'm trying to make a Kmap solving program in C and I've figured out how to make the truth table and the Kmap but now I wanna make pairs of 1s the the Kmap which is a 2D array, the pairing should only be done in powers of 2 like, 1 or 11 or 1111 or 11111111 and nothing in between here's an example.
Can somebody explain Functional iteration to me?
This is a part of page 58 from Introduction to Algorithms 3rd edition: https://imgur.com/5DC9ARv
Why the number of passes in radix sort is twice the number of digits?
Intuitively it should be number of digits, as we'll sort according to all the digits once, but its twice that and i don't know why.
Interesting competitive programming post in a blog but it's in Korean (I think)
My request is can some kind person who understands the language write a brief overview in English of the post, if a comprehensive translation is too much?
How to Improve Algorithmic Approach?
Hey Guys I have been coding for a long time in different languages and was building small games and stuff. What I felt was a lack of proper approach. I mean when I read someone else's code it seems too obvious but that thing doesn't hit instantly in my head.
