An environmental researcher is developing a software tool to monitor avian migration.

Write an algorithm, using pseudocode or a standard programming language of your choice, to perform the following tasks:

  • Prompt the user to input the total number of observation sessions, NNN, and store this value.
  • Repeatedly input the count of migrating birds spotted in each of the N N\,N sessions.
  • Calculate and output the total number of migrating birds recorded across all sessions.
  • Calculate and output the mean number of birds observed per session.
