Hello,

I have a list of Array of Points, i have to calculate min distance compare each & every element with one another to see
it will be done through the nested loop ?

(0.2,0.4,0.6)
(0.3,0.5,0.25)
(0.456,0.2345,0.12)
(0.178,0.124,0.98)
(0.123,0.456,0.123)

I have min distance formula only struggling to loop in efficient way. Please help

What I have tried:

for(int i = 0; i < 4; i++)
    for(int j = 1; j < i; j++)

Your outer loop needs to run from 0 to the second-to-last element of the list.

Your inner loop needs to run from outer loop + 1 to the last element of the list.

Eg:

C#

for (int i = 0; i < list.Count - 1; i++)
{
    for (int j = i + 1; j < list.Count; j++)
    {
        // Compare list[i] to list[j] here...
    }
}

This will compare every pair of elements from the list, without comparing the same pair twice.
