Connect Ropes with Minimum Cost

Given 'N' ropes, each having different lengths, your task is to connect these ropes into one single rope. The cost to connect two particular ropes is equal to the sum of their lengths. Please determine the minimum cost required to connect all the ropes.

Input:

The first line contains the integer 'N', representing the number of ropes. The second line contains 'N' space-separated integers indicating the lengths of the ropes, denoted as a1, a2, a3, ..., an.

Output:

The output should be a single integer - the minimum cost to connect all the ropes into one.

Example:

Input:

4 4 3 2 6

Output:

29

Constraints:

1

Accepted Answer

The task is to connect N ropes into one rope with minimum cost.

Sort the array of rope lengths in ascending order.
Initialize a variable to keep track of the total cost.
While there are more than one rope, take the two shortest ropes and connect them.
Add the cost of connecting the two ropes to the total cost.
Replace the two shortest ropes with the connected rope.
Repeat the above steps until only one rope remains.
Return the total cost.
