Write a program in $C$ which takes from the user two arrays of integers and combines those two arrays in one. In the newly produced array, the numbers of the first list are inverted and the numbers of the second list are tripled. Also, trace the code that you made and give explainations.

Example:

Enter the numbers of the first array: $1945$

Enter the numbers of the second array: $265$

The final array: $549161815$
