Get Login Code - IIT Roorkee Online Assessment

Problem Preview

"In a software company, each employee's login process involves two arrays: initialLogin of size n and standardLogin of size m. The security software transforms these arrays by repeatedly performing an operation: - Select any subsegment of either array and replace it with the sum of its elements. For example, the array [1, 5, 6, 8, 2] can be transformed into [12, 8, 2] by replacing the subsegment [1, 5, 6] with [12]. The goal is to maximize the length of equal arrays after performing the operations any number of times on both initialLogin and standardLogin. The login code is the maximum possible length of these equal arrays. If the arrays cannot be made equal through the operations, the initialLogin is considered invalid, and the result should be -1. Determine the login code based on the provided initialLogin and standardLogin, or return -1 if initialLogin is invalid. "
