➤ An algorithm is a step-by-step procedure or set of rules designed to perform a specific task or solve a particular problem. It is a systematic method that takes an input, processes it, and produces an output.
➤ Algorithms are generally created independent of underlying languages, i.e., an algorithm can be implemented in more than one programming language.
From the data structure point of view, the following are some important categories of algorithms:
➤ Algorithms are abstract concepts that describe a series of steps to solve a problem. They are not tied to any specific programming language.
➤ This means the same algorithm can be expressed in multiple programming languages, such as Python, Java, C++, etc.
➤ While the logic and structure of the algorithm remain the same, the syntax and specific functions may vary from one language to another.
➤ For example, a sorting algorithm like Bubble Sort can be implemented in various languages with different syntax but the same underlying logic.
Here’s how the Bubble Sort algorithm can be implemented in different programming languages:
def bubble_sort(arr):
n = len(arr)
for i in range(n):
for j in range(0, n-i-1):
if arr[j] > arr[j+1]:
arr[j], arr[j+1] = arr[j+1], arr[j]
return arr
public class BubbleSort {
public static int[] bubbleSort(int[] arr) {
int n = arr.length;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n-i-1; j++) {
if (arr[j] > arr[j+1]) {
int temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
return arr;
}
}
