            if (0 <= nr < rows and 0 <= nc < cols and 
                grid[nr][nc] != 1 and (nr, nc) not in visited):
                visited.add((nr, nc))
                queue.append((nr, nc, dist + 1))
    
    return -1  # No path found

# Time: O(rows * cols)
# Space: O(rows * cols)

3. Implement a thread pool.

import java.util.concurrent.*;
import java.util.concurrent.atomic.*;

public class ThreadPool {
    private final BlockingQueue<Runnable> taskQueue;
    private final Thread[] workers;
    private final AtomicBoolean isShutdown;
    
    public ThreadPool(int numThreads) {
        this.taskQueue = new LinkedBlockingQueue<>();
        this.workers = new Thread[numThreads];
        this.isShutdown = new AtomicBoolean(false);
        
        for (int i = 0; i < numThreads; i++) {
            workers[i] = new Worker();
            workers[i].start();
        }
    }
    
    public void execute(Runnable task) {
        if (isShutdown.get()) {
            throw new IllegalStateException("Pool is shutdown");
        }
        taskQueue.offer(task);
    }
    
    public void shutdown() {
        isShutdown.set(true);
        for (Thread worker : workers) {
            worker.interrupt();
        }
    }
    
    private class Worker extends Thread {
        public void run() {
            while (!isShutdown.get() || !taskQueue.isEmpty()) {
                try {
                    Runnable task = taskQueue.poll(100, TimeUnit.MILLISECONDS);
                    if (task != null) {
                        task.run();
                    }
                } catch (InterruptedException e) {
                    Thread.currentThread().interrupt();
                }
            }
        }
    }
}

4. Longest Increasing Subsequence.

def lengthOfLIS(nums):
    """
    DP with binary search - O(n log n)
    """
    if not nums:
        return 0
    
    # tails[i] = smallest tail of increasing subsequence of length i+1
    tails = []
    
    for num in nums:
        # Binary search for insertion point
        left, right = 0, len(tails)
        while left < right:
            mid = (left + right) // 2
            if tails[mid] < num:
                left = mid + 1
            else:
                right = mid
        
        if left == len(tails):
            tails.append(num)
        else:
            tails[left] = num
    
    return len(tails)

# Time: O(n log n)
# Space: O(n)

5. Design a distributed cache.

Key Components:
1. Cache Client - SDK for applications
2. Proxy/Router - Routes requests to appropriate shard
3. Cache Nodes - Store actual data
4. Consistent Hashing - Distribute keys across nodes
5. Replication - Primary-replica for availability
6. Eviction Policy - LRU/LFU for memory management

Consistency:
- Write-through: Write to cache and DB simultaneously
- Write-behind: Async write to DB
- Cache-aside: Application manages cache

Scaling:
- Horizontal: Add more nodes
- Rebalancing: Consistent hashing minimizes movement

---

6. Maximum subarray sum (Kadane's algorithm).

def maxSubArray(nums):
    """
    Kadane's algorithm - O(n)
    """
    max_sum = float('-inf')
    current_sum = 0
    
    for num in nums:
        # Either start new subarray or extend existing
        current_sum = max(num, current_sum + num)
        max_sum = max(max_sum, current_sum)
    
    return max_sum

# With start and end indices
def maxSubArrayWithIndices(nums):
    max_sum = float('-inf')
    current_sum = 0
    start = end = temp_start = 0
    
    for i, num in enumerate(nums):
        if current_sum + num < num:
            current_sum = num
            temp_start = i
        else:
            current_sum += num
        
        if current_sum > max_sum:
            max_sum = current_sum
            start = temp_start
            end = i
    
    return max_sum, start, end

# Time: O(n)
# Space: O(1)

7. Explain Java Memory Model.

Memory Areas:

1. Heap: Objects and arrays (shared across threads)
2. Stack: Local variables, method calls (per thread)
3. Method Area: Class metadata, static variables
4. PC Register: Current instruction address
5. Native Method Stack: Native method execution

Happens-Before Relationship:

// Changes in synchronized block visible to other threads
synchronized (lock) {
    sharedVar = newValue;
}

// volatile ensures visibility
volatile int sharedCounter;

Garbage Collection:

• Young Generation (Eden, Survivor spaces)
• Old Generation
• Metaspace (replacing PermGen)

8. Detect cycle in directed graph.

def hasCycle(graph):
    """
    DFS with three-color marking
    White: Not visited
    Gray: Being processed (in current DFS path)
    Black: Finished processing
    """
    WHITE, GRAY, BLACK = 0, 1, 2
    color = {node: WHITE for node in graph}
    
    def dfs(node):
        color[node] = GRAY
        
        for neighbor in graph.get(node, []):
            if color[neighbor] == GRAY:
                return True  # Back edge found
            if color[neighbor] == WHITE and dfs(neighbor):
                return True
        
        color[node] = BLACK
        return False
    
    for node in graph:
        if color[node] == WHITE:
            if dfs(node):
                return True
    
    return False

# Time: O(V + E)
# Space: O(V)

9. Implement an ATM system.

from threading import Lock
from enum import Enum

class TransactionType(Enum):
    WITHDRAWAL = 1
    DEPOSIT = 2
    BALANCE_INQUIRY = 3
    TRANSFER = 4

class ATM:
    def __init__(self, atm_id, initial_cash):
        self.atm_id = atm_id
        self.cash_available = initial_cash
        self.cash_denominations = {2000: 0, 500: 0, 100: 0}
        self.lock = Lock()
        self.transaction_log = []
    
    def authenticate_user(self, card_number, pin):
        """Validate card and PIN with bank"""
        # Call bank's authentication service
        pass
    
    def withdraw(self, account, amount):
        with self.lock:
            if amount > self.cash_available:
                return False, "Insufficient cash in ATM"

            self.cash_available -= amount
            self._log_transaction(TransactionType.WITHDRAWAL, account, amount)
            return True, notes
    
    def _calculate_notes(self, amount):
        """Greedy algorithm for note dispensing"""
        result = {}
        for denom in sorted(self.cash_denominations.keys(), reverse=True):
            if amount >= denom:
                count = min(amount // denom, self.cash_denominations[denom])
                result[denom] = count
                amount -= count * denom
        
        return result if amount == 0 else None

    """
    DP solution - O(n^2 * m) where m is avg word length
    """
    word_set = set(wordDict)
    n = len(s)
    
    # dp[i] = True if s[0:i] can be segmented
    dp = [False] * (n + 1)
    dp[0] = True
    
    for i in range(1, n + 1):
        for j in range(i):
            if dp[j] and s[j:i] in word_set:
                dp[i] = True
                break
    
    return dp[n]

# With path reconstruction
def wordBreakWithPath(s, wordDict):
    word_set = set(wordDict)
    n = len(s)
    
    dp = [[] for _ in range(n + 1)]
    dp[0] = [[]]
    
    for i in range(1, n + 1):
        for j in range(i):
            word = s[j:i]
            if dp[j] and word in word_set:
                for prev in dp[j]:
                    dp[i].append(prev + [word])
