Twice the minimum (Editorial)

Using a loop, find the minimum element of the array $min$. Then print its twice value.

Algorithm implementation

Read the input data. Compute the minimum element $min$ of the array.

scanf("%d", &n);
min = 100;
for (i = 0; i < n; i++)
{
  scanf("%lf", &a);
  if (a < min) min = a;
}

Print the answer — the twice value of the minimum element.

printf("%.2lf\n", 2 * min);

Python implementation

Read the input data.

n = int(input())
lst = list(map(float, input().split()))

Compute the minimum element of the list $lst$.

min_el = min(lst)

Print the answer — the twice value of the minimum element.

print(2 * min_el)
