recursive function for fibonacci series in java javascript
var fib = function(n) {
if (n === 1) {
return [0, 1];
} else {
var arr = fib(n - 1);
arr.push(arr[arr.length - 1] + arr[arr.length - 2]);
return arr;
}
};
console.log(fib(8));fibonacci series javascript using recursion explanation
1. fib(5) {
return fib(4) + fib(3);
2. fib(4) {
return fib(3) + fib(2);
3. fib(3) {
return fib(2) + fib(1);
4. fib(2) {
A= return 1;
};
5. fib(1) {
B= return 1;
};
C= return 2; // (1 + 1)
};
6. fib(2) {
D= return 1;
};
E= return 3; // (2 + 1)
};
7. fib(3) {
return fib(2) + fib(1);
8. fib(2) {
F= return 1;
};
9. fib(1) {
G= return 1;
};
H= return 2; // (1 + 1)
};
I= return 5; // (3 + 2)
