Cumulative source-code acceptance
Master cumulative delivery acceptance
Pass this private suite to enter Master at 420 skill.
What you need to build
Build a bounded, deterministic program combining the complete prior tree, including diagnostics-aware source, register-VM constraints, capsules, testing, and delivery reasoning.
Define master-report with these inputs:
| Argument | JIK type | Meaning |
|---|---|---|
items | vector of integers | Private delivery fixture. |
Expected result
Return [count sum checksum], where checksum is the left fold of (acc*31)+item.
Python-like pseudocode
def master_report(items):
total = 0
checksum = 0
for item in items:
total += item
checksum = checksum * 31 + item
return [len(items), total, checksum]The private suite checks returned values in 3 cases. Private inputs and expected values are never sent to the browser. Covered language features are recommended implementation tools; the evaluator does not inspect source structure.
