Extra Credit For extra credit, you can create a new file abc123P6ExtraCredit.c that solves the internship question we discussed in class. This file should have its own main() function. Prompt the user to input two integers "a" and "b" such that b> a. We want to convert "a into "b" using the following operations: +2, -1, or 3. For example, if we are currently at 4, then the next step could be either 6 (using the +2 operation), 3 (using the -1 operation), or 12 (using the *3 operation). We want to compute a minimum number of operations to convert "a" into "b. Compute an optimal solution for this problem and output the sequence of numbers in your solution. Extra credit given wil be 10+100/N points where N is the number of students who correctly submits the extra credit. No extra credit will be given for any late submission
