Calculate average from a given set of keys and values
Hello,
I am writing a script which expects as its input a hash with student names as the keys and marks as the values. The script then returns array of average marks for student scored 60-70, 70-80, and over 90.
Output expected
The test script so far I have written looks like this
I am able to store the input as hash with keys and its values but not able to calculate the average and give the output as expected. Any suggestions would be appreciated.
