Dynamic Programming (DP)
Dynamic programming is a technique for solving optimization problems by breaking them down into smaller subproblems and storing the solutions to these subproblems to avoid recomputing them. This can significantly improve the efficiency of the algorithm, especially for problems with overlapping subproblems.
Example:
Consider the problem of finding the minimum cost of reaching a destination from a starting point in a graph. We can use dynamic programming to solve this problem

Dynamic Programming (DP)
Dynamic programming is a technique for solving optimization problems by breaking them down into smaller overlapping subproblems. The solution to each subproblem is stored in a table, so that it can be reused later. This can significantly reduce the amount of computation required to solve the overall problem.
Example:
Consider the problem of finding the minimum cost of a path from a source node to a destination node in a graph. We can use dynamic programming to solve this problem

FIRST GENERATION (1941-1958)
Computers of this era used vacuum tubes to process information. Operators entered data and programs in special codes by means of punch cards.
SECOND GENERATION (1959-1964)
When vacuum tubes were replaced by transistors, computers became cheaper, smaller, consumed less power, and produced less heat. The increased circuit density allowed components to be positioned much closer to each other, saving space.
THIRD GENERATION
The development of integrated circuits, which placed

Quick Sort
Here’s a C implementation of the Quick Sort algorithm along with code to measure its execution time:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
// Function to swap two elements
void swap(int* a, int* b) {
int t = *a;
*a = *b;
*b = t;
}
// Partition function for Quick Sort
int partition(int arr[], int low, int high) {
int pivot = arr[high]; // Pivot element
int i = (low Analysis of Sorting Algorithms: Quick Sort, Merge Sort, and Selection Sort

Working with Database Files: Deleting Fields and Records
Deleting a Field
To delete a field in a database file using forms, follow these steps:
- Open the table and start editing.
- Select the field you want to remove.
- Go to the Edit menu and choose Delete Field.
- Stop editing the table.
Deleting a Record
To delete a record in a database file using forms, follow these steps:
- Open the table and start editing.
- Select the records you want to delete.
- Go to the Edit menu and choose Delete Record.
- Stop editing the table.
