what kind of algorithm is mystery Lovely and hear your
- 00:25
potential answers ueno immediately The answer is b c or
- 00:31
d the algorithm returns an array so it must be
- 00:35
a sort algorithm Alright well we can see that there
- 00:38
is variable called current index that ita rates from one
- 00:41
until the array lane way could also see that the
- 00:43
algorithm finds the lowest value and puts it into the
- 00:46
current index Well this is a characteristic of selection sort
- 00:51
The algorithm continuously finds the lowest value and then puts
- 00:55
it in the lowest available index So d is going
- 00:58
to be our answer Next time we'll look a linear
