Copying a std::array

The code already creates array<int, 3> a = {1, 2, 3};, copies it with array<int, 3> b = a;, and then changes b[0] to 99.

Print two lines: the text a[0]:, a space and the first element of a, then the text b[0]:, a space and the first element of b.

Expected Output:

a[0]: 1↵
b[0]: 99↵

= newline. The output ends with a newline — print one after the last line.
