# Amazon Online Assessment (OA) - Connect Ropes

Given `n`

ropes of different lengths, you need to connect these ropes into one rope.
You can connect only `2`

ropes at a time. The cost required to connect `2`

ropes is equal to the `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

The input consists of an argument:

`ropes`

: an int array representing the rope length

### Output

Return the min possible cost required to connect all ropes.

### Examples

#### Example 1:

##### Input: `[8, 4, 6, 12]`

##### Output: `58`

##### Explanation:

The optimal way to connect ropes is as follows

- Connect the ropes of length
`4`

and`6 (cost is 10)`

. Ropes after connecting:`[8, 10, 12]`

- Connect the ropes of length
`8`

and`10 (cost is 18)`

. Ropes after connecting:`[18, 12]`

- Connect the ropes of length
`18`

and`12 (cost is 30)`

.

Total cost to connect the ropes is `10 + 18 + 30 = 58`

#### Example 2:

##### Input: `[20, 4, 8, 2]`

##### Output: `54`

#### Example 3:

##### Input: `[1, 2, 5, 10, 35, 89]`

##### Output: `224`

#### Example 4:

##### Input: `[2, 2, 3, 3]`

##### Output: `20`
