Answer 3

all(x<=y for (x,y) in zip(l,l[1:]))

Answer 4

public static bool listordened(int[] listt)
{

for (int i = listt.Length - 1; i >= 1; i--)
{
for (int j = i- 1; j >= 0; j--)
{
if (listt[i] < listt[j])
{
return false;
}

}
}

return true;
}

Answer 5

If you want a faster one (O(n))

public static bool listordened(int[] listt)
{

for (int i = listt.Length - 1; i >= 1; i--)
{
if (listt[i] < listt[i-1])
{
return false;
}
}

return true;
}
}
