Build a strong foundation in algorithmic concepts, covering algorithms, asymptotic analysis, sorting, searching, and divide and conquer techniques.

Computer Science Bootcamp

Algorithms are step-by-step instructions or guidelines for solving specific problems or accomplishing specific tasks. Analyzing algorithms is important to understand their efficiency, scalability, and overall performance, thus enabling us to decide on their implementation and optimization. This module introduces us to algorithmic paradigms, asymptotic analysis, lists, sorting and searching algorithms, and techniques such as divide and conquer. We’ll start by discovering techniques like brute force, greedy algorithms, divide and conquer, and dynamic programming. Then, we’ll learn to analyze algorithms using asymptotic notations, focusing on Big O and solving challenges like removing even integers, merging sorted lists, and finding minimum values. By the end of this module, we will have gained expertise in sorting and searching algorithms, like selection sort, merge sort, and binary search, and applied the divide and conquer technique to solve challenges, like finding peak elements and missing numbers.

Fundamental Algorithms in Python

# Statement
Given a list of integers, `lst`, remove all the even integers from the list.

**Constraints:**

- $1 \leq$ `lst.length` $\leq 10^3$
- $-10^5 \leq$ `lst[i]` $\leq  10^5$

# Examples
 


Help me debug only the remove_even. I don't need the corrected code.I don't want explanations or code reviews. Just provide me the exact and to-the-point error that helps me run the code successfully on the test cases provided.

Please help me understand why this code failed for the last failed test case. Please don't give me the corrected code. Just provide me exact and to-the-point advice on how to correct the code so that it runs successfully on the test cases provided. 

Your current task is to review remove_even function And Answer the following questions: First, Ensure that code makes proper use of the List  data structure? If yes, then appreciate the learner; otherwise, give some hints on the List  data structure.Second, Does the code follow proper language guidelines? If the code is lengthier, check if the code is following a modularity approach with multiple functions. If yes, appreciate the learner; otherwise, suggest language guidelines.At the end, review the code.

Please provide a brief time complexity analysis of the remove_even function at the start in a sentence. Then, use bullet points to explain the complexity details. While calculating time complexity, include the time complexity of built-in Python functions invoked by the code. The Answer should be to the point and short.

Please provide a brief space complexity analysis of the remove_even function at the start in a sentence. Then, use bullet points to explain the space complexity details. While calculating space complexity, include the space complexity of built-in Python functions invoked by the code. The Answer should be to the point and short.
