Energy State Calculation

You are given a list of activities performed by an individual. Each activity has an associated energy cost as follows:

• working: 8
• exercising: 5
• socializing: 3
• relaxing: -2
• sleeping: -8

Your task is to compute the Net Energy Score (NES) using the formula:

$$NES = \sum_{i=1}^{n} cost(activity_i)$$

Then, determine the energy state based on the following criteria:

• If \(NES < 0\), output Exhausted.
• If \(0 \le NES < 10\), output Tired.
• If \(10 \le NES < 20\), output Balanced.
• If \(NES \ge 20\), output Energetic.

Note: Any activity not listed in the above table should be ignored.

inputFormat

The first line contains an integer n representing the number of activities. The next n lines each contain a string representing an activity.

outputFormat

Output a single line containing one of the strings: Exhausted, Tired, Balanced, or Energetic, which corresponds to the energy state.
