Today, we tackle two master-level programming questions that have stumped even the most seasoned coders. So, if you find yourself thinking, "write my C++ assignment," you've come to the right place!
Question 1: The Tower of Hanoi Dilemma
Let's start with a classic problem that tests your recursive prowess: The Tower of Hanoi. In this scenario, we are tasked with moving a tower of n disks from one rod to another, with the constraint that no disk may be placed on top of a smaller disk.
<pre><em>#include <iostream></em><br><br><em>void towerOfHanoi(int n, char source, char auxiliary, char destination) {</em><br><em> if (n == 1) {</em><br><em> std::cout << "Move disk 1 from " << source << " to " << destination << std::endl;</em><br><em> return;</em><br><em> }</em><br><br><em> towerOfHanoi(n - 1, source, destination, auxiliary);</em><br><em> std::cout << "Move disk " << n << " from " << source << " to " << destination << std::endl;</em><br><em> towerOfHanoi(n - 1, auxiliary, source, destination);</em><br><em>}</em><br><br><em>int main() {</em><br><em> int numDisks = 3; // Change this to the desired number of disks</em><br><em> towerOfHanoi(numDisks, 'A', 'B', 'C');</em><br><em> return 0;</em><br><em>}</em></pre>
Here, we use the Tower of Hanoi as a demonstration of recursive problem-solving in C++. The towerOfHanoi function takes in the number of disks (n) and the source, auxiliary, and destination rods. The base case handles the scenario with only one disk, while the recursive calls ensure the proper movement of the tower.
Question 2: Dynamic Programming Marvel - Longest Common Subsequence
Our second challenge involves dynamic programming, a powerful technique for optimizing recursive solutions. The task is to find the Longest Common Subsequence (LCS) between two given sequences.
<pre><em>#include <iostream></em><br><em>#include <vector></em><br><br><em>int longestCommonSubsequence(const std::string& str1, const std::string& str2) {</em><br><em> int m = str1.length();</em><br><em> int n = str2.length();</em><br><br><em> std::vector<std::vector<int>> dp(m + 1, std::vector<int>(n + 1, 0));</em><br><br><em> for (int i = 1; i <= m; ++i) {</em><br><em> for (int j = 1; j <= n; ++j) {</em><br><em> if (str1[i - 1] == str2[j - 1]) {</em><br><em> dp[j] = dp[i - 1][j - 1] + 1;</em><br><em> } else {</em><br><em> dp[j] = std::max(dp[i - 1][j], dp[j - 1]);</em><br><em> }</em><br><em> }</em><br><em> }</em><br><br><em> return dp[m][n];</em><br><em>}</em><br><br><em>int main() {</em><br><em> std::string sequence1 = "ABCBDAB";</em><br><em> std::string sequence2 = "BDCAB";</em><br><em> int result = longestCommonSubsequence(sequence1, sequence2);</em><br><br><em> std::cout << "Length of Longest Common Subsequence: " << result << std::endl;</em><br><em> return 0;</em><br><em>}</em></pre>
In this example, we implement the LCS problem using a dynamic programming approach. The longestCommonSubsequence function takes two strings as input and returns the length of the LCS. The dynamic programming table (dp) is filled iteratively based on the characters of the input strings.
By exploring these master-level programming questions, we hope to enhance your understanding of recursive problem-solving and dynamic programming in C++.
