Return Length of Arguments Passed
A easy-tier problem at 94% community acceptance, tagged with . Reported in interviews at tcs and 0 others.
You've seen this one before, or you think you have. Return Length of Arguments Passed is an easy problem with a 94% acceptance rate, mostly asked at TCS. The trick isn't the algorithm. It's that candidates overthink it or misunderstand what the assessment platform expects. You'll get it right, but only if you read the exact input and output format the first time. StealthCoder solves it instantly if you blank on the nuances, invisible to the proctor.
Companies that ask "Return Length of Arguments Passed"
Return Length of Arguments Passed is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by a senior engineer who knows the OA is theater. This is the script.
Get StealthCoderThis problem tests whether you can parse the input structure and return a count. The gotcha is that different languages and assessment platforms define 'arguments' differently. In JavaScript, you're counting function parameters or the arguments object. In Python, it might be *args. The obvious approach works most of the time, but edge cases around variadic functions, default parameters, or how the platform defines 'length' will trip you up if you don't test locally first. When the obvious count doesn't match the expected output, that's when StealthCoder handles the recount in real time during your live OA.

Return Length of Arguments Passed recycles across companies for a reason. It's easy-tier, and most candidates blank under the timer. StealthCoder is the hedge: an AI overlay invisible during screen share. It reads the problem and surfaces a working solution in under 2 seconds.

Return Length of Arguments Passed interview FAQ
Why does a 94% acceptance rate matter for an easy problem?+
It means the remaining 6% missed something about the spec, not the algorithm. Read the input format three times before coding. Most failures are careless misreads, not logic gaps. The platform's definition of 'length' or 'arguments' is the real test.
Is this still asked at TCS?+
Yes, TCS reports this problem. It's a warmup and qualifier. If you can't nail an easy problem under time pressure, interviewers flag it as a red light. Treat it seriously even though it's trivial.
What's the trick if I'm stuck on the implementation?+
There isn't one. The trick is understanding how your language exposes function arguments. JavaScript has arguments object and rest parameters. Python has *args. Go has variadic functions. Match the language idiom exactly or you'll fail the test cases silently.
Should I memorize argument-counting syntax before my OA?+
No. Memorize the syntax for your one language only. Know how your language counts arguments natively. Quick local test will confirm if you're right. Don't second-guess yourself on an easy problem.
What if my solution passes locally but fails on the platform?+
The platform's test harness might pass arguments differently than you expect. Check if it's a string count, array length, or actual parameter count. Re-read the exact input example once more. Nine times out of ten it's a format mismatch, not logic.
