Encryption Validity Description A hijacker is attempting to break into a system protected by a list of encryption keys. The strength of this encryption is determined by the highest degree of divisibility among the elements in the key list. The degree of divisibility of an element in the key list is defined as the number of elements in the list (greater than 1) that divide it evenly. The higher this number, the stronger the encryption. For example, in the key list [2, 4, 8, 5, 2] , the element 4 has a degree of divisibility of 3 because three elements — 2 , 4 , and 2 — divide it evenly. The encryption strength is calculated as: encryption_strength = highest_degree_of_divisibility × 10 5 This value represents the number of attempts a hijacker would need to make to crack the encryption. You are given a list of encryption keys, the hijacker's testing speed (in keys per second), and the validity period (in seconds). Your task is to determine whether the hijacker can crack the encrypti
