Interview Questions & Answers
1. Docker DNS Resolution Fix
Resolve "temporary failure in name resolution" errors by properly configuring Docker DNS settings at the daemon or runtime level. Add DNS servers (8.8.8.8, 1.1.1.1) to daemon.json, use --dns flags in docker run, verify /etc/resolv.conf inside containers, and test domain resolution with ping and curl. Essential for container networking, external API calls, package downloads, and internet-dependent applications in isolated network environments.

4. Redundant Connection
def find_redundant_connection(edges: list[list[int]]) -> list[int]:
parent = [i for i in range(len(edges) + 1)]
rank = [1] * (len(edges) + 1)
def find(n):
p = parent[n]
while p != parent[p]:
parent[p] = parent[parent[p]]
p = parent[p]
return p
def union(n1, n2):
p1, p2 = find(n1), find(n2)
if p1 == p2:
return False
if rank[p1] > rank[p2]:
parent[p2] = p1
rank[p1] += rank[p2]
else:
parent[p1] = p2
rank[p2] += rank[p1]
return True
for u, v in edges:
if not union(u, v):
return [u, v]
return []
5. Minimum Interval to Include Each Query
def min_interval(intervals: list[list[int]], queries: list[int]) -> list[int]:
intervals.sort(key=lambda x: x[0])
sorted_queries = sorted([(q, i) for i, q in enumerate(queries)])
min_heap = []
res = [-1] * len(queries)
idx = 0
for q_val, original_i in sorted_queries:
while idx < len(intervals) and intervals[idx][0] <= q_val:
left, right = intervals[idx]
size = right - left + 1
heapq.heappush(min_heap, (size, right))
idx += 1
while min_heap and min_heap[0][1] < q_val:
heapq.heappop(min_heap)
if min_heap:
res[original_i] = min_heap[0][0]
return res
