Introduction
Logical programs are important to build logic as well as they are important during interviews. Most companies ask these logical programs to test the skills of candidates.
Here we created a list of the top most-asked logical programs which are important for cracking interviews and also helpful to build logical thinking.
We are going to provide a solution for each and every logical program so you don't need to search for them.

| 1 | Print a triangle pattern | Pattern using stars (*) |
| 2 | Check if a number is prime | Returns true if prime, false otherwise |
| 3 | Find the factorial of a number | Uses recursion or iteration |
| 4 | Reverse a string | Reverses the given input string |
| 5 | Check if a string is a palindrome | Reads the same forward and backward |
| 6 | Find the Fibonacci series up to N | Prints Fibonacci sequence up to N terms |
| 7 | Find the GCD of two numbers | Greatest common divisor using Euclidean algorithm |
