May 8, 2023 · Given two list of lists of equal length, write a Python program to merge the given two lists, according to the first common element of each sublist. Examples: Input : lst1 = [[1, 'Alice'], [2, 'Bob'], [3, 'Cara']] lst2 = [[1, 'Delhi'], [2, 'Mumbai'], [3, 'Chennai']] Output : [[1, 'Alice', 'Delhi'], [2, 'Bob', 'Mumbai'], [3, 'Cara', 'Chennai']]Input

A merge sort algorithm is an efficient sorting algorithm based on the divide and conqueralgorithm. It divides a collection (array) of elements into single units and then merges them in an orderly fashion. Let's see an example to understand how merge sort works. We are going to use the merge sort algorithm to sort this array of numbers: 4, 10, 6, 14...
If we want to implement merge sort with Java, here's what that would look like: Let's break the code down. Above, we created our array of numbers. After that, we called the mergeSortmethod to sort the numbers. Then we looped through the array of sorted numbers and printed them to the console. We got the midpoint of the array by dividing the array l...
The logic here is exactly the same as in the last section. Above, we implemented the merge sort algorithm using Python. You can find an explanation of how the code works in the last section. The time complexity of merge sort is O(n*Log n) for all cases (best, average and worst).
In this article, we saw learned how the merge sort algorithm works. We then saw some examples and how to apply it in our Java and Python code. Happy coding!
Aug 6, 2024 · Creating a simple matrix using Python. Method 1: Creating a matrix with a List of list. Here, we are going to create a matrix using the list of lists. Python. matrix = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]] print("Matrix =", matrix) Output: Matrix = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]
Merge Sort is a kind of Divide and Conquer algorithm in computer programming. In this tutorial, you will understand the working of merge sort with working code in C, C++, Java, and Python.
4 Answers. Sorted by: 43. Use numpy.concatenate: >>> import numpy as np. >>> np.concatenate((A, B)) matrix([[ 1., 2.], [ 3., 4.], [ 5., 6.]]) answered Nov 24, 2013 at 19:59.
Jul 22, 2023 · Merge Sort is a popular sorting algorithm that follows the divide-and-conquer approach. It efficiently sorts an array or a list by recursively dividing it into smaller subarrays, sorting them individually, and then merging them back together.
