edges and vertices

[fenil]

Given N = 4, A = [1, 3], B = [2, 4] function should return 10. The graph contains two edges: (1, 2) and (3, 4).

 

function ec($n, array $a, array $b){

}

Is there a question in there somewhere or are you asking someone to program it for you. If the latter then you need to post it here.

Here you are. Now it returns 10

function ec($n, array $a, array $b){
    return 10;
} 

We are not going to do your assignment for you.

 Given N = 4, A = [1, 3], B = [2, 4] function should return 10. The graph contains two edges: (1, 2) and (3, 4). We can assign following values to the vertices: 4, 3, 2, 1.

 The sum of values at the edges' endpoints is (4 + 3) + (2 + 1) = 10.

 

how to find edges of vertices and sum of values at the edges' endpoints ?

 

function ec($n, array $a, array $b){  }
