Python Program to print the diamond shape
The looping features in python can be used to create many nicely formatted diagrams using various characters from the keyboard. One such shape is diamond shape which will involve multiple loops. This is because we have to print the character both vertically and horizontally. Also we have to take care of the shape gradually growing from top till middle and then gradually shrinking from middle till the bottom. For this reason, we will use two for loops each containing one more for loop inside it.Below is the code for creating the diamond shape.Exampledef Shape_of_Diamond(shape): a = 0 for m in ...
Read MoreContingency Table in Python
A contingency table is a table showing the distribution of one variable in rows and another variable in columns. It is used to study the correlation between the two variables. It is a multiway table which describes a dataset in which each observation belongs to one category for each of several variables. Also It is basically a tally of counts between two or more categorical variables. Contingency tables are also called crosstabs or two-way tables, used in statistics to summarize the relationship between several categorical variables.The contingency coefficient is a coefficient of association which tells whether two variables or datasets ...

Text EditorThis will be used to type your program. Examples of few editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi.Name and version of text editor can vary on different operating systems. For example, Notepad will be used on Windows and vim or vi can be used on windows as well as Linux, or UNIX.The files you create with your editor are called source files and for C++ they typically are named with the extension .cpp, .cp, or .c.A text editor should be in place to start your C++ programming.C++ CompilerThis is an actual C++ ...
Read MoreCons of using the whole namespace in C++
In C++, we use different namespaces. We can also create our own namespaces. For example, generally, we use standard namespace called std. We write the syntax like:using namespace std;In the standard library, it contains common functionality you use in building your applications like containers, algorithms, etc. If names used by these were out in the open, for example, if they defined a queue class globally, you'd never be able to use the same name again without conflicts. So they created a namespace, std to contain this change.The using namespace statement just means that in the scope it is present, make ...
Read MoreFind the closest pair from two sorted arrays in c++
Suppose we have two sorted arrays and a number x, we have to find the pair whose sum is closest to x. And the pair has an element from each array. We have two arrays A1 [0..m-1] and A2 [0..n-1], and another value x. We have to find the pair A1[i] + A2[j] such that absolute value of (A1[i] + A2[j] – x) is minimum. So if A1 = [1, 4, 5, 7], and A2 = [10, 20, 30, 40], and x = 32, then output will be 1 and 30.We will start from left of A1 and right from ...
Read MoreProduct of non-repeating (distinct) elements in an Array in C++
We are given with an array of repeating or duplicate elements and the task is to find the product of all those elements which are non-repeating or distinct in the given array and display the results.ExampleInput-: arr[] = {2, 1, 1, 2, 3, 4, 5, 5 } Output-: 120 Explanation-: Since 1, 2 and 5 are repeating more than once so we will take them into consideration for their first occurrence. So result will be 1 * 2 * 3 * 4 * 5 = 120 Input-: arr[] = {1, 10, 9, 4, 2, 10, 10, 45, 4 } ...
Read MoreProgram for Mobius Function in C++
Given a number n; the task is to find the Mobius function of the number n.What is Mobius Function?A Mobius function is number theory function which is defined by$$\mu(n)\equiv\begin{cases}0\1\(-1)^{k}\end{cases}$$n= 0 If n has one or more than one repeated factorsn= 1 If n=1n= (-1)k If n is product of k distinct prime numbersExampleInput: N = 17 Output: -1 Explanation: Prime factors: 17, k = 1, (-1)^k 🠠(-1)^1 = -1 Input: N = 6 Output: 1 Explanation: prime factors: 2 and 3, k = 2 (-1)^k 🠠(-1)^2 = 1 Input: N = 25 Output: 0 Explanation: Prime factor is ...
Read MorePython Program for Odd-Even Sort / Brick Sort
In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given an array, we need to sort it using brick sort.Here we have two phases: Odd and Even Phase. In the odd phase, bubble sort is performed on odd indexed elements and in the even phase, bubble sort is performed on even indexed elements.Now let’s observe the solution in the implementation below−Exampledef oddEvenSort(arr, n): # flag isSorted = 0 while isSorted == 0: isSorted = 1 temp = 0 ...
Read MorePython Program for Merge Sort
In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given an array, we need to sort it using the concept of merge sortHere we place the maximum element at the end. This is repeated until the array is sorted.Now let’s observe the solution in the implementation below −Example#merge function def merge(arr, l, m, r): n1 = m - l + 1 n2 = r- m # create arrays L = [0] * (n1) R = [0] * (n2) # Copy data to arrays ...
Read MoreFind smallest subarray that contains all elements in same order in C++
Suppose we have two arrays of size m and n, The task is to find minimum length subarray in the first array, that contains all the elements if the second array. Element in second array may be present in the large array in non-contiguous but order must be same. So if two arrays are like A = [2, 2, 4, 5, 8, 9], and B = [2, 5, 9], then the output will be 5. As the smallest subarray of A, will be [2, 4, 5, 8, 9]. Here all elements like [2, 5, 9] are in the same order. ...
