Learn how to implement popular data structures and algorithms in our next Python project with hands-on examples.

Python for Programmers

Data structures and algorithms are among the most fundamental concepts of computer science. This module is a detailed review of some of the most common data structures and algorithms, such as stack, linked lists, doubly linked lists, binary trees, binary search trees, and so on. With implementation details, thorough explanations, and hands-on coding exercises, we’ll gain the confidence to solve any problem related to our project.

Data Structures and Algorithms in Python

Recursive implementations  are always less space-consuming then iterative implementations. 

Recursive implementations are always less space-consuming then iterative implementations.

```python
base * (exp -1)* pow(base,exp)
```

Fill in the blank for the following recursive function which calculates the power of a base raised to an exponent:
```python
def pow(base,exp):
    if exp == 0: 
        return 1
    else:
        return ___________
```

Fill in the blank for the following recursive function which calculates the power of a base raised to an exponent:
<pre><code class="language-python">def pow(base,exp):
 if exp == 0: 
 return 1
 else:
 return ___________
</code></pre>

What is the output of the following code?
```python
def fibonacci(n):
    if n==1:
        return 0
    elif n==2:
        return 1
    else:
        return fibonacci(n-1)+fibonacci(n-2) 
print(fibonacci(7)) 
```

What is the output of the following code?
<pre><code class="language-python">def fibonacci(n):
 if n==1:
 return 0
 elif n==2:
 return 1
 else:
 return fibonacci(n-1)+fibonacci(n-2) 
print(fibonacci(7)) 
</code></pre>
