please solve it and explain the code to me

Integer numin is read from input. Given the integer vector hourlyMiles with the size of numin, write a for loop to output the integers in the first half of hourlyMiles in reverse order. Separate the integers with an asterisk surrounded by spaces (" * "). Ex. If the input is 8 48647788106108109119 then the output is: 88776448 Note: The vector size is always even
