Hey these are some questions in C that I'm getting confused on in class. It has to deal with recursion. Any help will be greatly appreciated.

10. Write a recursive function Min(A) to find the smallest integer in an integer array A[n]. (Hint: Define an auxiliary function Min2(A.kj) that finds the smallest integer in A[k:)], and let Min(A) = Min2(A, O, n - 1).) 13. Describe in words what the following function P(int n) does: T void PDigit(int d) auxiliary procedure used below in P to write the */ /* character corresponding to the digit d */ printf("%c", (char) ( (int)O' + 0)); 5 void P(int n) /* assume n is a non-negative integer * 10 if (n
