0/5

A forestry researcher is designing a program for a survey drone to analyze canopy data over a specified plot.

Write an algorithm in pseudocode or a programming language of your choice to:

  • Ask the user to input the number of trees in the sample plot and store this value.
  • Repeatedly take a tree height (in metres) as input, until the heights for the specified number of trees have been entered.
  • Calculate and output the total combined height of all the trees in the sample plot.
  • Calculate and output the average tree height for the sample plot.
