-# <div align="Center">3 Sum Problem</div>
-## The 3Sum problem is a popular problem where you are given an array of integers and need to find all unique triplets in the array that sum up to a specific target (usually zero). It’s a variation of the subset sum problem and is commonly used to practice array manipulation and sorting.

-### For Example :
-```
-#include <stdio.h>
-#include <stdlib.h>
-
-void threeSum(int arr[], int n) {
-    // Sorting the array
-    qsort(arr, n, sizeof(int), compare);

-

-
-### Explanation of Merge Sort:
-- **Divide**: The array is divided into two halves.
-- **Conquer**: Each half is sorted recursively.
-- **Combine**: The sorted halves are merged to form the sorted array.

-## The Traveling Salesman Problem (TSP) involves finding the shortest route that allows a salesman to visit all given cities exactly once and return to the starting city. It is a popular optimization problem with real-world applications in logistics and transportation.
