About Time-Complexity:
Your program is functional, but it runs too slowly. Or perhaps your neat little piece of code is running just fine, but slower than that other, longer one. In computer science, the Big-O notation is frequently used to describe the efficiency or complexity of an algorithm. Practically speaking, it serves as a gauge to determine whether your function is effective and whether it needs to be improved.
As you continue your education, time-complexity will play a bigger role in your development environment. You'll eventually be able to evaluate your software and determine which programs fit into which time complexity categories (constant, linear, quadratic, exponential, logarithmic). To better understand how Time-Complexity works in your code and in real life, we'll be breaking down the fundamentals in this guide.
O(N²) — Quadratic Time:
An algorithm with quadratic time complexity has performance that is squarely correlated with the size of the input data set (think of Linear, but squared). This temporal complexity will appear in our applications anytime we nest over numerous iterations in the data sets.
Let's look at the cards again. How to eliminate all the cards with the same number if, for example, you chose the first card in the deck. You would need to go through the deck and eliminate any duplicate cards. You would repeat the process with the next card, the next, and so on until you reached the last card in the deck after you were certain that all the duplicates had been eliminated. An illustration of quadratic time complexity is this.
