Answer / siva kumar

for example :
Here a is three(3).

calling fun(3) in main function.
FUN(3) {
calling fun(2) {
calling fun(1) {
calling fun(0) {
N>0 found.
}
printed 0
calling second fun(-1) {
N>0 found.
}
}
printed 1
calling second fun(0) {
N>0 found.
}
}
printed 2
calling second fun(1) {
calling fun(0) {
N>0 found.
}
printed 0
calling second fun(-1) {
N>0 found.
}
}
}
