code=>

//get minimum and maximum and then

class Algo

{

static solve(arr:Array<number>)

{

let max=0;

let min=0;

max=arr[0];

min=arr[0];

for(var i=0;i<arr.length;i++)

{

if(arr[i+1]>max)

{

max=arr[i+1]

}

if(arr[i+1]<min)

{

min=arr[i+1]

}

}

return {"minSum":this.sumWithMaxMin(arr,max),"maxSum":this.sumWithMaxMin(arr,min)}

}

static sumWithMaxMin(arr,n):number

{

let sum=0;

for(let i=0;i<arr.length;i++)

{

if(arr[i]!=n)

{

sum+=arr[i];

}

}

return sum;

}

}

var o=Algo.solve([1,2,3,4,5]);

console.log(o.maxSum);

console.log(o.minSum);
