Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Use std::sort and a comparator to transform the array [7, 2, 4, 1, 6, 3] so that even numbers come first and odd numbers come second, with each group in ascending order. Print the resulting array in the format [2, 4, 6, 1, 3, 7].

[2, 4, 6, 1, 3, 7]
