The length of the integer array is <code>N<\/code>, and<br \/>\n        each integer has a value between <code>0<\/code> and <code>100<\/code>.<br \/>\n        There may be duplicate numbers among these integers, and those numbers should be sorted and printed according to their occurrences.\n    <\/p>\n<h3>Input Format<\/h3>\n<p>\n        The first line contains an integer <code>N<\/code> (1 \u2264 <code>N<\/code> \u2264 100,000), and<br \/>\n        the second line contains <code>N<\/code> integers separated by spaces.\n    <\/p>\n<h3>Output Format<\/h3>\n<p>\n        Print the sorted integers in one line, separated by spaces.\n    <\/p>\n<h2>Example Input<\/h2>\n<pre>5\n3 4 3 2 1<\/pre>\n<h2>Example Output<\/h2>\n<pre>1 2 3 3 4<\/pre>\n<h2>Problem Solving Process<\/h2>\n<h3>1. Understanding the Problem<\/h3>\n<p>\n        We need to sort the given array while considering duplicate numbers to obtain a sorted format.<br \/>\n        This problem can be easily solved using a common sorting algorithm.\n    <\/p>\n<h3>2. Approaching the Problem<\/h3>\n<p>\n        In JavaScript, we can easily sort an array using the built-in method <code>sort()<\/code>.<br \/>\n        The <code>sort()<\/code> method converts the array elements to strings and sorts them based on Unicode values.<br \/>\n        However, to sort integers, we need to provide a comparison function.\n    <\/p>\n<h3>3. Implementation Method<\/h3>\n<p>\n        &#8211; To sort the input array, we first read the array.<br \/>\n        &#8211; Then, we use the <code>sort()<\/code> method along with a comparison function to sort the array.<br \/>\n        &#8211; Finally, we print the sorted array.\n    <\/p>\n<h3>4. JavaScript Code Implementation<\/h3>\n<pre>\n        \/\/ Reading input\n        const fs = require('fs');\n        const input = fs.readFileSync('\/dev\/stdin').toString().trim().split('\\n');\n\n        const N = parseInt(input[0], 10);\n        const numbers = input[1].split(' ').map(Number);\n\n        \/\/ Sorting\n        numbers.sort((a, b) =&gt; a - b);\n\n        \/\/ Output\n        console.log(numbers.join(' '));\n    <\/pre>\n<h3>5. Time Complexity<\/h3>\n<p>\n        The time taken to sort the provided array is generally O(N log N).<br \/>\n        This is because JavaScript&#8217;s <code>sort()<\/code> method operates based on efficient sorting algorithms like quicksort and mergesort.\n    <\/p>\n<h3>6. Space Complexity<\/h3>\n<p>\n        The additional memory space used is O(N).<br \/>\n        This is needed for creating a copy of the array or for storing the sorted results.\n    <\/p>\n<h2>Conclusion<\/h2>\n<p>\n        This problem is a simple sorting problem that can be easily solved using JavaScript&#8217;s built-in methods.<br \/>\n        It is important to write efficient code while considering the time complexity of sorting algorithms during problem-solving.<br \/>\n        I hope you have learned about sorting algorithms and how to use JavaScript&#8217;s <code>sort()<\/code> method through this lecture.\n    <\/p>\n<p><\/body><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Problem Description This is a problem to sort numbers in a given integer array.
