These days, many companies are evaluating applicants’ algorithm and problem-solving skills through coding tests. This time, we will take a look at the process of solving a problem with the topic of sorting cards. Sorting cards is one of the very simple yet frequently asked questions, requiring a fundamental understanding of algorithms and data structures.<\/p>\n
We are trying to sort cards that have numbers written on them for a card game. The number of cards is The first line contains the number of cards Print the sorted card numbers separated by spaces.<\/p>\n We can use the following approach to solve the problem.<\/p>\n Now let’s write the code. Below is the JavaScript code to solve the card sorting problem.<\/p>\n Let’s explain each part of the code we wrote.<\/p>\n The The We will test the code we wrote to verify that it works correctly with various inputs.<\/p>\n In this tutorial, we explored how to solve the card sorting problem using JavaScript’s array methods. Additionally, we had a chance to understand the approach and the role of each function through code writing. Problems like this are frequently asked in algorithm tests, so it is important to improve problem-solving skills through practice.<\/p>\n For those who want to practice more advanced algorithm problems, please refer to the links below:<\/p>\n With that, we will conclude the JavaScript coding test course. Always strive to prepare for successful coding tests!<\/p>\n <\/body><\/p>\n","protected":false},"excerpt":{"rendered":"N<\/code>, and each card has an integer number from 1<\/code> to N<\/code>.

sortCards Function<\/h3>\n
sortCards<\/code> function takes an array of card numbers and returns it sorted in ascending order. It uses JavaScript’s built-in sort<\/code> method, along with an arrow function to compare the sizes of the numbers.<\/p>\nMain Function<\/h3>\n
main<\/code> function performs the following tasks:<\/p>\n\n
prompt<\/code> to input the number of cards.<\/li>\nprompt<\/code> again to input the card numbers and passes them as a string.<\/li>\nsplit<\/code> method to convert the space-separated string into an array, and uses the map<\/code> method to convert each element into a number.<\/li>\nsortCards<\/code> function to get the sorted array.<\/li>\njoin<\/code> method and outputs it to the console.<\/li>\n<\/ul>\nTesting and Validation<\/h2>\n
Test Case 1<\/h3>\n
