Software testing is the process of determining the performance of the developed program. It is also made to improve the product and reduce faults and difficulties with it. We have something called the STLC, or Software Testing Life Cycle, for professional software testing endeavors.Software testers are experts that are in charge of the testing process. Smaller and simpler software products need just a few, or perhaps a single, testers, while large, complete software products necessitate a professional testing staff.Software testing job descriptions range from testers and test analysts to testing managers and test designers. There are several software testing certifications ... Read More
What is an artifact, exactly?No, we're not talking about ancient relics. The sort of artifact we're discussing is one that has to do with software development.Whether you're a novice or a seasoned developer, you'll encounter software artifacts. They're critical components of any piece of software, from a simple webpage to a more complicated application.The software development process will be significantly more difficult than it needs to be if artifacts are not correctly produced and preserved.Continue reading to discover all you need to know about software artifacts and what you'll need to know going ahead.ArtifactAn artifact is a by-product of software ...

The linear function named scipy.linalg.solve_banded is used to solve the banded matrix equation. The form of this function is as follows −scipy.linalg.solve_banded(l_and_u, ab, b, overwrite_ab=False, overwrite_b=False, debug=None, check_finite=True)This linear function will solve the equation ax = b for x where a is a banded matrix.The banded matrix a is stored in ab by using the matrix diagonal ordered form as follows −ab[u + i - j, j] == a[i, j]The example of ab is given as follows −* a01 a12 a23 a34 a45 a00 a11 a22 a33 a44 a55 a10 a21 a32 a43 a54 * a20 a31 ...

scipy.cluster.hierarchy.fcluster(Z, t, criterion=’inconsistent’depth=2, R=None, monocrat=None)− The fcluster() method forms flat clusters from the hierarchical clustering. This hierarchical clustering is defined by the given linkage matrix, identifying a link between clustered classes.Below is given the detailed explanation of its parameters −ParametersZ− ndarrayIt represents the hierarchical clustering which is encoded with the linkage matrix.t− scalarThe value of t depends on the type of criteria. For ‘inconsistent’, ‘distance’, and ‘monocrit’ criteria, the value of t represents the threshold to apply when forming flat clusters. On the other hand, for ‘maxclust’, and ‘maxclust_monocrit’ criteria, the value of t represents the maximum number of clusters ... Read More
The linear function named scipy.linalg.solveh_banded is used to solve the banded matrix equation. In the below given example we will be solving the banded system Hx = b where −$$\mathrm{H} = \begin{bmatrix} 8 & 2-1j&0 &0 \ 2+1j & 5& 1j & -2-1j0\ 0 & -1j& 9& \ 0 & 0& -2+1j& 6 \end{bmatrix} \mathrm{b}=\begin{bmatrix} 1\ 1+1j\ 1-2j\ 0 \end{bmatrix}$$For our example below, we will be putting the upper diagonal in the array hb −Examplefrom scipy.linalg import solveh_banded hb = np.array([[0, 2-1j, 1j, -2-1j], [8, 5, 9, 6 ]]) b = np.array([1, 1+1j, 1-2j, 0]) x = solveh_banded(hb, b) ...

For some classes of software and certain kinds of software projects, agile software engineering is an acceptable compromise between traditional software engineering and agile software engineering. Agile procedures may provide high-quality systems in a short amount of time. It emphasizes the need for ongoing communication and cooperation between developers and consumers.For effective execution of offshore software development projects with qualities such as shorter time to market and changing company demands, we use agile software development process models. Iterative software development with frequent client delivery is a basic strategy in agile software development that immediately solves one of the primary issues ... Read More
Subarrays are the contiguous part of an array. For example, we consider an array [5, 6, 7, 8], then there are ten non-empty subarrays like (5), (6), (7), (8), (5, 6), (6, 7), (7, 8), (5, 6, 7), (6, 7, 8) and (5, 6, 7, 8).In this guide, we will explain every possible information to find the number of subarrays with odd sums in C++. For finding the number of subarrays with the odd sum, we can use different approaches, so here is a simple example for it −Input : array = {9, 8, 7, 6, 5} Output : 9 ... Read More
In this article, we will solve the number of subarrays having sum in a given range using the C++ program. We have an array arr[] of positive integers, and a range {L, R} and we have to calculate the total number of subarrays having sum in the given range form L to R. So here is the simple example for the problem −Input : arr[] = {1, 4, 6}, L = 3, R = 8 Output : 3 The subarrays are {1, 4}, {4}, {6}. Input : arr[] = {2, 3, 5, 8}, L = 4, ... Read More
If you have ever used C ++, you must know what subarrays are and how useful they are. As we know that, in C++, we can solve multiple mathematical problems easily. So in this article, we will explain the complete information on how we can find M odd numbers with the help of these subarrays in C++.In this problem, we need to find many subarrays formed with the given array and integer m where each subarray contains exactly m odd numbers. So here is the simple example of this approach −Input : array = { 6, 3, 5, 8, 9 ... Read More
In this article, we will solve the problem of finding the number of subarrays whose maximum and minimum elements are the same using C++. Here is the example for the problem −Input : array = { 2, 3, 6, 6, 2, 4, 4, 4 } Output : 12 Explanation : {2}, {3}, {6}, {6}, {2}, {4}, {4}, {4}, {6, 6}, {4, 4}, {4, 4} and { 4, 4, 4 } are the subarrays which can be formed with maximum and minimum element same. Input : array = { 3, 3, 1, 5, 1, 2, 2 } Output : 9 ... Read More
