Q41. private int func3(int m, int n) { if (m < n) return 0; else return 1 + func3(m-n, n); } Refer to the code above. What is the value of func3(-5, 1)? a. -5 b. 0 c. 1 d. 5

Q50. private int func1(int m, int n) { if (m==n || n==1) return 1; else return func1(m-1,n-1) + n*func1(m-1,n); } What precondition must exist in order to prevent the code above from infinite recursion? a. m > = 0 and n >= 0 b. m >= 0 and n >= 1 c. m >= 1 and n >= 0 d. m >= 1 and n >= 1
