Min Cost to Connect Ropes problem solution using PriorityQueue using C#

Given n ropes of different lengths, we need to connect these ropes into one rope. We can connect only 2 ropes at a time. The cost required to connect 2 ropes is equal to sum of their lengths. The length of this connected rope is also equal to the sum of their lengths. This process is repeated until n ropes are connected into a single rope. Find the min possible cost required to connect all ropes. Input: ropes = [ 8 , 4 , 6 , 12 ] Output: 58 Explanation: The optimal way to connect ropes is as follows 1. Connect the ropes of length 4 and 6 (cost is 10 ). Ropes after connecting: [ 8 , 10 , 12 ] 2. Connect the ropes of length 8 and 10 (cost is 18 ). Ropes after connecting: [ 18 , 12 ] 3. Connect the ropes of length 18 and 12 (cost is 30 ). Total cost to connect the ropes is 10 + 18 + 30 = 58 public static void Demo() { //int[] Ropes = { 4, 3, 2, 6 }; //int[] Ropes = { 8, 4, 6, 12 }; int[] Ropes = { 1, 2, 5, 10, 35, 89...
