Answer 1

In search, you confused value < values[mid] and value > values[mid].

Also, search should return true, not mid, on finding the value.

In sort, you seem to attempt a bubble sort. In bubble sort, you compare adjacent elements values[k] and values[k+1], no i involved in the comparison/swapping part.
