<p>A company is planning to interview <code>2n</code> people. Given the array <code>costs</code> where <code>costs[i] = [aCost<sub>i</sub>, bCost<sub>i</sub>]</code>, the cost of flying the <code>i<sup>th</sup></code> person to city <code>a</code> is <code>aCost<sub>i</sub></code>, and the cost of flying the <code>i<sup>th</sup></code> person to city <code>b</code> is <code>bCost<sub>i</sub></code>.</p>
|
|
|
|
<p>Return <em>the minimum cost to fly every person to a city</em> such that exactly <code>n</code> people arrive in each city.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> costs = [[10,20],[30,200],[400,50],[30,20]]
|
|
<strong>Output:</strong> 110
|
|
<strong>Explanation: </strong>
|
|
The first person goes to city A for a cost of 10.
|
|
The second person goes to city A for a cost of 30.
|
|
The third person goes to city B for a cost of 50.
|
|
The fourth person goes to city B for a cost of 20.
|
|
|
|
The total minimum cost is 10 + 30 + 50 + 20 = 110 to have half the people interviewing in each city.
