Consider the following two functions.
void fun1(int n) {
if(n == 0) return;
printf("%d", n);
fun2(n - 2);
printf("%d", n);
}
void fun2(int n) {
if(n == 0) return;
printf("%d", n);
fun1(++n);
printf("%d", n);
}
The output printed when $\text{fun1}(5)$ is called is
- $53423122233445$
- $53423120112233$
- $53423122132435$
- $53423120213243$
