LEFT JOIN returns all rows from the left table and the matched rows from the right table
RIGHT JOIN returns all rows from the right table and the matched rows from the l...
Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. Merge sort is a divide and conquer algorithm that divides the input array into two halves, recursively sorts the two halves, and then merges the sorted halves.
Bubble sort has a time complexity of O(n^2) in worst case scenario, while merge sort has a time comple...
