Coding Challenges and Problem-Solving

For software engineering roles, you may be asked to complete coding challenges during your interview or as a take-home assignment. These challenges are designed to assess your problem-solving skills, coding ability, and understanding of data structures and algorithms.

Here are some examples of coding challenges you might encounter:

1. Implement a function to reverse a linked list

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def reverseLinkedList(head):
    prev = None
    current = head
    
    while current is not None:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    
    return prev

2. Find the longest palindromic substring in a given string

def longestPalindrome(s):
    if not s:
        return ""
    
    start = 0
    max_length = 1
    
    for i in range(len(s)):
        # Check for odd-length palindromes
        left, right = i, i
        while left >= 0 and right < len(s) and s[left] == s[right]:
            if right - left + 1 > max_length:
                start = left
                max_length = right - left + 1
            left -= 1
            right += 1
        
        # Check for even-length palindromes
        left, right = i, i + 1
        while left >= 0 and right < len(s) and s[left] == s[right]:
            if right - left + 1 > max_length:
                start = left
                max_length = right - left + 1
            left -= 1
            right += 1
    
    return s[start:start+max_length]

3. Implement a function to find the k-th largest element in an unsorted array
