To prepare effectively for the Amazon Hiring Challenge on HackerRank, focus on the following structured approach:

Core Areas to Focus On

1. Data Structures:

   • Arrays/Strings: Sliding window, two-pointers, hash maps (e.g., longest substring without repeats, anagrams).
   • Linked Lists: Cycle detection, reversal, merging (e.g., merge k sorted lists).
   • Trees/Graphs: Traversals (BFS/DFS), LCA, shortest paths (Dijkstra), topological sorting.
   • Heaps: Priority queues for problems like merge k sorted lists or k closest points.
   • Tries: Autocomplete, word search.

2. Algorithms:

   • Dynamic Programming: Knapsack, LCS, edit distance, coin change (memoization and bottom-up approaches).
   • Greedy Algorithms: Task scheduling, interval problems.
   • Graph Algorithms: BFS/DFS, union-find, cycle detection.

3. System Design/OOD: Design patterns, class structures (e.g., LRU cache, parking lot).

Common Amazon Problems

• Task Scheduler: Calculate idle slots using max frequency tasks.
• Rotting Oranges: BFS to track infection spread.
• Critical Connections: Tarjan's algorithm for graph bridges.
• Two Sum: Hash map for O(n) solution.
• Word Ladder: BFS for shortest transformation path.

Example Solutions

1. Task Scheduler:

def leastInterval(tasks, n):

    freq = [0] * 26

    for task in tasks:

        freq[ord(task) - ord('A')] += 1

    freq.sort()

    max_freq = freq[-1]

    idle = (max_freq - 1) * n

    for f in freq[:-1][::-1]:

        idle -= min(max_freq - 1, f)

    return len(tasks) + max(0, idle)

2. Rotting Oranges:

from collections import deque



def orangesRotting(grid):

    rows, cols, q, fresh = len(grid), len(grid[0]), deque(), 0

    for i in range(rows):

        for j in range(cols):

            if grid[i][j] == 2: q.append((i, j))

            elif grid[i][j] == 1: fresh += 1

    if not fresh: return 0

    dirs = [(0,1), (1,0), (-1,0), (0,-1)]

    minutes = -1

    while q:

        minutes += 1

        for _ in range(len(q)):

            x, y = q.popleft()

            for dx, dy in dirs:

                nx, ny = x + dx, y + dy

                if 0 <= nx < rows and 0 <= ny < cols and grid[nx][ny] == 1:

                    grid[nx][ny] = 2

                    fresh -= 1

                    q.append((nx, ny))

    return minutes if fresh == 0 else -1

Preparation Tips

• Practice Coding: Use platforms like LeetCode (Amazon tagged) and HackerRank.
• Time Complexity: Aim for optimal solutions (e.g., O(n) for arrays, O(log n) for binary search).
• Edge Cases: Test for empty inputs, single elements, large values, etc.
• Mock Tests: Simulate timed conditions to improve speed and accuracy.

Common Pitfalls

• Off-by-one errors: Double-check loop boundaries.
• Space Management: Avoid redundant data structures; optimize for space.
• Recursion Limits: Prefer iterative approaches for deep recursion in Python.

By methodically covering these areas and practicing problem-solving under timed conditions, you'll enhance your readiness for Amazon's HackerRank challenge.
