# Assume we have a File class whose constructor takes a filepath string as an argument. It has a single method called write, which persists bytes directly to disk.
# f = File('/tmp/my/file.txt')
# f.write(b"hello world")
# Write a wrapper class for the file object which allows us to buffer the writes in-memory. The wrapper class, BufferedFile is initialized with a File class object and a buffer size. It has two methods: write and flush. The data should be flushed to disk when the buffer is full, or on demand with a method called flush. All bytes must be stored in the buffer first before being written to disk. The buffer cannot use more memory than the max bytes allowed.
# Example usage:
# f = File('/tmp/my/file.txt')
# buf_size = 1000
# b = BufferedFile(f, buf_size)
# b.write(b"hello world")
# b.flush()
The logs to be an "M" (match)., all the words in the log should be present in that Query. For ex - "M: Loading snapshot failed no stacktrace available; Q=2,3,4" is a match with Q 2,3,4 because - "Stacktrace", "loading failed", and "snapshot loading" - each of these words are present in the Log "Loading snapshot failed no stacktrace available".livetail_stream = [
"Q: database",
"Q: Stacktrace",
"Q: loading failed",
"L: Database service started",
"Q: snapshot loading",
"Q: fail",
"L: Started processing events",
"L: Loading main DB snapshot",
"L: Loading snapshot failed no stacktrace available",
]
livetail_output = [
"ACK: database; ID=1",
"ACK: Stacktrace; ID=2",
"ACK: loading failed; ID=3",
"M: Database service started; Q=1",
"ACK: snapshot loading; ID=4",
"ACK: fail; ID=5",
"M: Loading main DB snapshot; Q=4",
"M: Loading snapshot failed no stacktrace available; Q=2,3,4",

System design
“Design a mint-like app, but it only had transactions from credit/debit cards and analytics and notification if transaction goes over a threshold.”
系统设计不难，一些关键的点在我们的面试辅助中都有提到。候选人经过我们的面试辅导，也在面试中能对一些系统设计中涉及的概念能娓娓道来。
