Different Sorting Methodologies

Hi everyone! In this blog, I’ll be sharing some basic sorting algorithms that I learned as a 2nd-year engineering student. Sorting is one of the most important topics in Data Structures. What is Sorting? Sorting means arranging data in a specific order (ascending or descending). It helps in: Faster searching Better data organization Improving efficiency of algorithms Common Sorting Algorithms Bubble Sort Compare adjacent elements Swap if they are in the wrong order Repeat until sorted Example: [5, 3, 2] → [3, 5, 2] → [3, 2, 5] → [2, 3, 5] Time Complexity: O(n²) Simple but very slow for large data Selection Sort Find smallest element Place it at the beginning Repeat for remaining array Time Complexity: O(n²) Fewer swaps than Bubble Sort Insertion Sort Pick element and insert into correct position Like sorting playing cards Time Complexity: O(n²) Works well for small or nearly sorted arrays Merge Sort Divide array into halves Sort each half Merge them Time Complexity: O(n log n) Very eff
