What will be the best case complexity for merging two sorted arrays in one sorted array both are of different sizes M and N?

Time Complexity O(M + N), where ‘M’ is the size of the array, ‘ARR1’ and ‘N’ is the size of the array ‘ARR2’. Merging elements of ‘ARR1’ and ‘ARR2’ in ‘ARR3’ takes O(M + N) time.

What is the time complexity of finding the median of two sorted arrays using the method of counting while merging?

Time and space complexity analysis

1. We need to traverse each element to merge both sorted arrays.
2. Overall time complexity = Time complexity of merging + Time complexity of finding median = O(n) + O(1) = O(n)
3. We are using 2n size extra space for merging, so space complexity = O(n)

What is the complexity of merging two sorted arrays?

The complexity is O(m log n). There are m iterations of the loop. Each insertion into a sorted array is an O(log n) operation. Therefore the overall complexity is O (m log n).

What is the complexity of the merge operation on two arrays each of size N 2?

The complexity of merge sort is O(nlogn) and NOT O(logn). The divide step computes the midpoint of each of the sub-arrays. Each of this step just takes O(1) time. The conquer step recursively sorts two subarrays of n/2 (for even n) elements each.

What is the intersection of two arrays?

The intersection of two arrays is a list of distinct numbers which are present in both the arrays. The numbers in the intersection can be in any order.

What is the time complexity of finding the median of a sorted list?

Time Complexity to find median = O(n Log n) as we need to sort the array first.

What is relative sort array leetcode?

Relative Sort Array Leetcode Solution In this problem, we are given two arrays of positive integers. All elements of the second array are distinct and are present in the first array. However, the first array can contain duplicate elements or elements that are not in the second array.

What is the default value of an array of integers?

When you declare an array, each element of the array is set to a default initial value. For integers, the default value is 0. What do you think the default value is for doubles? Write a program that declares a double array of length 4, prints the values, assigns a value to each element, and prints the values again.

What is the output array of a sorted matrix?

Given k sorted arrays of size n each, merge them and print the sorted output. Explanation: The output array is a sorted array that contains all the elements of the input matrix. Explanation: The output array is a sorted array that contains all the elements of the input matrix.

How to create a subproblem with half the size of arrays?

Compare the middle elements of arrays arr1 and arr2, let us call these indices mid1 and mid2 respectively. Let us assume arr1 [mid1] k, then clearly the elements after mid2 cannot be the required element. Set the last element of arr2 to be arr2 [mid2]. In this way, define a new subproblem with half the size of one of the arrays.
