Predict the output:
C
#include <stdio.h>void crazy(int n, int a, int b){ if (n <= 0) return; crazy(n - 1, a, b + n); printf("%d %d %d \n",n,a,b); crazy(n-1, b, a+n);}int main(){ crazy(3, 4, 5); return 0;} |
(A)
1 4 10 2 4 8 1 8 6 3 4 5 1 5 9 2 5 7 1 7 7
(B)
3 4 5 1 4 10 2 4 8 1 8 6 1 5 9 2 5 7 1 7 7
(C)
1 4 10 2 4 8 1 8 6 3 4 5
(D)
3 4 5 1 5 9 2 5 7 1 7 7
Answer: (A)
Explanation:
Call(3,4,5)
- crazy(3, 4, 5) calls crazy(2, 4, 5 + 3)
- crazy(2, 4, 8) calls crazy(1, 4, 8 + 2)
- crazy(1, 4, 10) calls crazy(0, 4, 10 + 1)
- crazy(0, 4, 11) returns immediately as the base case is reached. and prints 1, 4, 10.
- crazy(0, 11,4). return as the base case is reached.
Now, we wrap up the recursive calls:
- call crazy(2,4,8) prints 2,4,8 and again call for crazy(1,8, 6). which will print 1,8,6.
- call crazy(3,4,5) prints 3,4,5 and again call for crazy(2,5, 7). which will again call for (1,5,9) prints 1 5 9.
- call crazy (2,5,7) prints 2,5,7 and again call for crazy(1,7,7), which will print 1,7,7.
Hence (A) is the correct Option.
