function miniMaxSum(arr) {
    // Write your code here
    const max = arr.sort((a,b) => b-a).slice(0,4).reduce((a,b)=> a+b,0)
    const min = arr.sort((a,b) => b-a).reverse().slice(0,4).reduce((a,b)=> a+b,0)

    console.log(min,max)
}

const minmax = arr => 
  console.log(`min:${arr.sort().slice(0,-1)
  .reduce((a,b)=>a+b)} max:${arr.sort()
  .slice(1).reduce((a,b)=>a+b)}`)
