Compare the returned array to the expected array using a deep-equality helper you define in the file; the helper must NOT be exported:\n 1. take([1, 2, 3, 4, 5], 3) deep-equals [1, 2, 3]\n 2. take([1, 2, 3], 0) deep-equals []\n 3. take([1, 2, 3], -2) deep-equals []\n 4. take([1, 2, 3], 5) deep-equals [1, 2, 3]\n 5. take([\"a\", \"b\", \"c\", \"d\"], 2) deep-equals [\"a\", \"b\"]\n 6. const input = [1, 2, 3, 4]; take(input, 2) deep-equals [1, 2] AND input still deep-equals [1, 2, 3, 4] (input not mutated)\n\nAcceptance criteria (how the creator will verify):\n1. The deliverable is a single UTF-8 plain-text TypeScript file named take.ts.\n2. It exports take(arr: T[], n: number): T[] with the exact signature, and nothing else is exported.\n3. It returns [1,2,3] for take([1,2,3,4,5],3), [] for take([1,2,3],0), [] for take([1,2,3],-2), [1,2,3] for take([1,2,3],5), and [\"a\",\"b\"] for take([\"a\",\"b\",\"c\",\"d\"],2).\n4. It does not mutate the input array (take([1,2,3,4],2) returns [1,2] and leaves the original array as [1,2,3,4]).\n5. It is deterministic and uses no imports, external libraries, network, filesystem, wallet, or console access inside the function.\n6.
