How to Count Occurrences of an Element in a List/Array/String
In this video, I will show you how to count the occurrences of an element or value inside a string, list, or array. We will use linear search to do this. First, we initialize a counter variable to zero. We traverse through the array. When we encounter that element or value, we increment the counter variable. This is an important computer science concepts that students need to know. In the next video, I will show you how to count frequencies of elements in an array.

Differences between Tight Big O, Tight Big Omega, and Tight Big Theta
zhlédnutí 65Před dnem
In this video, I will explain the differences between Tight Big O, Tight Big Omega, and Tight Big Theta. I will show you how to prove or disprove Big Omega Ω. For example, you are asked to prove that a function 2n^3 - 7n 1 is Ω(n^3). By the definition of big O, f(n) is O(g(n)) if you can find a positive constant c and a positive integer nₒ such that f(n) is less than or equal to c times g(n), f...

In this video, I will explain stacks often taught in a data structures and algorithms course. Stacks can be implemented with an array or a linked list. If a stack is implemented by an array, it is called an ArrayStack. But if the stack is implemented by a linked list, then it is called a LinkedStack. Stacks have a special property called FILO, or First in Last Out. I show plenty of examples in ...

In this video, I will show you how to prove the area of an ellipse using calculus integration. Recall that an ellipse is a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane which does not intersect the base. The area formula of an ellipse is A = pi*ab, where a...

In this video, I will show you how to prove the area of a triangle using integral calculus. The area of a triangle is the one over two times the base times the height. First, you use the area formula under a function, which is equal to the integral from a to b of f(x), where f(x) is a curve of a straight line. Then, we evaluate that integral. This is an important concept to master for Calculus ...

In this video, I will show you how to solve the indefinite integral of cos(2x) using u substitution. This is an important topic for students taking Calculus, whether it is AP Calculus or Calculus in university. The idea behind u-substitution is to simply the integrand. For example, we can simplify 1/(2x 4) with 1/u where u=2x 4. The second step is to differentiate u with respect to x, then plug...

      That's correct as well! I recommend using two recursion methods (since mergesort and quicksort also use two recursion methods). I took a course on only recursion and I find that using the one recursion method takes longer to write. But also it doesn't matter if you use one or two. I prefer to use two though :)

      I took these problems from the textbook "Early Transcendentals - 9th Edition" by James Steward. It's a famous textbook used by many teachers and professors.
