Analyzing Algorithm Time Complexity

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

This section analyzes the complexity of several well-known algorithms: binary search, selection sort, and Tower of Hanoi. Analyzing Binary Search The binary search algorithm presented in BinarySearch.java, searches for a key in a sorted array. Each iteration in the algorithm contains a fixed number of operations, denoted by c. Let T(n) denote the time complexity for a binary search on a list of n elements. Without loss of generality, assume n is a power of 2 and k = logn. Since a binary search eliminates half of the input after two comparisons, Ignoring constants and nondominating terms, the complexity of…

While working for my last client, we needed to extend an existing feature. We had to import an Excel file with a list of guests into a group event. Think of importing all the guests to a wedding reception at a hotel. "You only have to add your changes to this existing component. It's already working." That was what our Product Owner told us. I bet you have heard that, too. The next thing we knew was that the "already-working" component had issues. The original team was laid off, and we couldn't get our questions answered or count on them…

Fui commitar e deu branco. E agora?

Esses dias, navegando no X, me deparei com a seguinte imagem E achei engraçado, porque eu e você provavelmente já nos vimos nessa situação: adicionamos os arquivos e ficamos literalmente travados pensando o que colocar de mensagem no commit. Muitas vezes os arquivos são em pastas e contextos diferentes, o que dificulta ainda mais a pensar em uma mensagem condizente. E é aí que mora o problema: Quando commitamos todos os arquivos com o famoso git add . fica muito difícil resumir em uma frase o que foi feito naquele commit. E você no fundo sabe que uma hora ou…

Vector and Stack Classes

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, java, learning, programming, software

Vector is a subclass of AbstractList, and Stack is a subclass of Vector in the Java API. The Java Collections Framework was introduced in Java 2. Several data structures were supported earlier, among them the Vector and Stack classes. These classes were redesigned to fit into the Java Collections Framework, but all their old-style methods are retained forcompatibility. Vector is the same as ArrayList, except that it contains synchronized methods for accessing and modifying the vector. Synchronized methods can prevent data corruption when a vector is accessed and modified by two or more threads concurrently. For the many applications that…
