**Days Needed For Becoming Orbitax Engineers** You are the lead Trainer at Orbitax, and you’ve been given the responsibility to mentor a group of n fresh joiners who aspire to become Orbitax Engineers. The onboarding process for each joiner involves two critical phases: a training phase followed by a self-learning phase. The journey for each joiner is unique, as they require different amounts of time for training and self-learning. Here’s how it works: 1. Training Phase: Before a joiner can dive into self-learning, they need to undergo hands-on training from you. You have a packed schedule, so you can only train one joiner per day. Each joiner has a specific number of days they require for training. For example, for a joiner if Training Time is 5, he needs 5 days of your training, but those days don’t have to be consecutive. However, for him all 5 days must be completed before he can move on to self-learning. 2. Self-Learning Phase: Once a joiner completes his training, they move on to self-learning, which takes a fixed number of days for each joiner. During this phase, they study independently and don’t require your direct involvement. For example, for a joiner if Self Learning Time is 4, he needs 4 days of self-learning after completing his training. Your challenge is to create an efficient plan. Since you can train only one joiner a day, you must carefully choose the order in which you train them so that all joiners complete both phases and become Orbitax Engineers as quickly as possible. Determine the minimum number of days required for all joiners to finish both phases (training and self-learning) and officially become Orbitax Engineers. Note: You have the flexibility to decide in what order you train the joiners. Once a joiner completes their training phase, they automatically start their self-learning phase and work on it independently.
