Two python dictionaries may contain some common keys between them. In this article we will find how to get the difference in the keys present in two given dictionaries.With setHere we take two dictionaries and apply set function to them. Then we subtract the two sets to get the difference. We do it both ways, by subtracting second dictionary from first and next subtracting first dictionary form second. Those keys which are not common are listed in the result set.Example Live DemodictA = {'1': 'Mon', '2': 'Tue', '3': 'Wed'} print("1st Distionary:", dictA) dictB = {'3': 'Wed', '4': 'Thu', '5':'Fri'} print("1st Distionary:", ...

In this problem, we are given an array arr[] of N integers and two index values x and y. Our task is to create a program to find the Maximum sum increasing subsequence from a prefix and a given element after prefix is must in C++.Problem DescriptionWe will find the maximum sum of increasing sequence till index x and including the element at index y.Let’s take an example to understand the problem, Inputarr[] = {1, 5, 9, 131, 6, 100, 11, 215}, x = 4, y = 6Output26ExplanationWe will take the subsequence till index 3 and then at last include ...

In this tutorial, we will be discussing a program to find maximum Sum Increasing Subsequence.For this we will be provided with an array containing N integers. Our task is to pick up elements from the array adding to the maximum sum such that the elements are in sorted orderExample Live Demo#include using namespace std; //returning the maximum sum int maxSumIS(int arr[], int n) {    int i, j, max = 0;    int msis[n];    for ( i = 0; i < n; i++ )       msis[i] = arr[i];    for ( i = 1; i < n; ...

Suppose you are given a list but we want to convert it to dictionary. Dictionary elements hold two values are called key value pair, we will use in case of value. The elements of the list become keys and non will remain a placeholder.With dictThe dict() constructor creates a dictionary in Python. So we will use it to create a dictionary. The fromkeys method is used to create the dictionary elements.Example Live DemolistA = ["Mon", "Tue", "Wed", "Thu", "Fri"] print("Given list: ", listA) res = dict.fromkeys(listA) # New List print("The list of lists:", res)OutputRunning the above code gives us ...

In this problem, we are given a circular array cirArr[]. Our task is to create a program to find the Maximum sum in circular array such that no two elements are adjacent in C++.Problem DescriptionFor the circular array, we need to find the maximum sum sum of elements of the array such that adjacent elements cannot be taken i.e. we need to take alternate elements.Circular Array is a special type of array in which the last element of the array is connected to the first element.Let’s take an example to understand the problem, InputcirArr[] = {4, 1, 5, 3, 2}Output9ExplanationThe ...

In this problem, we are given a rectangular grid of size 2 x n. Our task is to create a program to find the Maximum sum in a 2 x n grid such that no two elements are adjacent in C++.Problem DescriptionTo find the maximum sum, we cannot select elements that are adjacent to the current element, vertically, horizontally or diagonally.Let’s take an example to understand the problem, InputrectGrid[2][] =389 411Output13Explanationall possible sums areIf we start from rectGrid[0][0] i.e. 3, then we can add only 9 or 1. The maxSum is 12.If we start from rectGrid[1][0] i.e. 4, then we ... Read More

There may be a situation when we need to convert the elements in the list into a list in itself. In other words, create a list which is nested as its elements are also lists.Using iterationThis is the novel approach in which we take each element of the list and convert it to a format of lists. We use temporary list to achieve this. Finally all these elements which are converted to lists are group together to create the required list of lists.Example Live DemolistA = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri'] print("Given list:", listA) new_list = [] # Creating ...

In this problem, we are given three arrays arr1[], arr2[], and arr3[] all of size N. Our task is to create a program to find the Maximum sum from three arrays such that picking elements consecutively from same is not allowed in C++.Problem DescriptionWe will find the maximum sum by choosing N elements. i=th element can be chosen of the sum from the i-th element of the array i.e. ith sum is from arr1[i]/ arr2[i]/ arr3[i]. Also, keep in mind that we cannot choose two consecutive elements that can be chosen from the same array.Let’s take an example to understand ... Read More

We know the arithmetic operations between different arrays happens monthly if the arrays are of equal size awesome required specific size. But there are scenarios when we can take erase of unequal size and still apply arithmetic operations on them by enhancing one of the arrays by filling array with smaller ndim prepended with '1' in its shape. So basically broadcasting and array means changing its shape to any required shape.Rules of array BoradcastingArray with smaller ndim than the other is prepended with '1' in its shape.Size in each dimension of the output shape is maximum of the input sizes ...

In this problem, we are given a binary tree consisting of positive numbers. Our task is to create a program to find the Maximum sum from a tree with adjacent levels not allowed in C++.Code DescriptionHere, we will find the maximum sum of node of the tree in such a way that the sum does not contain nodes from two adjacent levels of the tree.Let’s take an example to understand the problem, Output21ExplanationTaking root as starting level, sum = 5 + 3 + 8 + 1 = 17 Taking sub-child of root as starting level, sum = 2 + 6 ...
