Summary
The problem is about sorting a pile of cards in a specific order. The key concept involved is arrays and data structures. Given a list of numbers representing the cards in a pile, you need to sort them in ascending order.
Detailed Explanation
To solve this problem, we can use a simple array-based algorithm like Bubble Sort or Quick Sort. Here's a step-by-step breakdown of the solution using Bubble Sort:
- Initialize an array
cardswith the given numbers. - Define a function
bubbleSortthat takes thecardsarray as input and returns the sorted array. - In the
bubbleSortfunction:- Iterate through the
cardsarray until no more swaps are needed (i.e., the array is sorted). - For each iteration, iterate through the array from the first element to the second-to-last element.
- Compare adjacent elements and swap them if they're in the wrong order.
- Iterate through the
- Return the sorted
cardsarray.
Here's an example of what the algorithm would look like for a sample input:
Input: [5, 2, 8, 3, 1, 6, 4]
Output: [1, 2, 3, 4, 5, 6, 8]
The time complexity of Bubble Sort is O(n^2), where n is the length of the input array. The space complexity is O(1) since we only use a small amount of extra memory to store the sorted array.
Optimized Solutions
Java
public int[] sortCards(int[] cards) {
for (int i = 0; i < cards.length - 1; i++) {
for (int j = 0; j < cards.length - i - 1; j++) {
if (cards[j] > cards[j + 1]) {
int temp = cards[j];
cards[j] = cards[j + 1];
cards[j + 1] = temp;
}
}
}
return cards;
