Our client just contacted us and said that they are planning from time to time provide us four integers instead
of two and three
Hint: What would be a universal/generic solution for dealing with such clients? Should we be proactive and
write methods with 5, 6, 7, etc. parameters in advance?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2ec814c7-90f3-4435-9bb8-fcbab3f733ac%2F9ec55c54-996c-42f7-9508-80decfe00e97%2Fs2hl12_processed.png&w=3840&q=75)
