Practice: Slices and Arrays

The following exercises will help solidify your knowledge of slices.

1. Starting from a nil []int, append one value at a time, printing length and capacity after each call until capacity reaches 16. Predict the sequence before you run it.

2. Create s:= []int{1, 2, 3, 4, 5}. Take a subslice of length 3 starting at index 1, using a three-part slice expression to set its capacity to 3. Append 100 to the subslice. Print both slices and explain why the parent is unchanged.

3. Use slices.EqualFunc together with strings.EqualFold to compare two []string values for case-insensitive equality. Cover the cases of equal, unequal, and different lengths.
