Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine the number of students not currently standing in their correct positions. Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine the number of students not currently standing in their correct positions.

The function in Python is as follows:

def heightChecker(heights):

   expected = []

   count = 0

   for i in range(len(heights)):

       expected.append(heights[i])      

   expected.sort()

   for i in range(len(heights)):

       if expected[i] != heights[i]:

           count+=1  

   return count

Step-by-step explanation:

Required

Function to return the number of out of position students

See comment for complete question

This defines the function. It receives the heights as a parameter, from the main

def heightChecker(heights):

This initializes a list, (expected list)

   expected = []

This initializes the count of out of position students

   count = 0

This iterates through the original list

   for i in range(len(heights)):

The list item is then appended to the expected list

       expected.append(heights[i])      

This sorts the expected list in ascending order

   expected.sort()

This iterates through the original and the expected lists

   for i in range(len(heights)):

If list elements at the same index are not the same, count is incremented by 1

       if expected[i] != heights[i]:

           count+=1  

This returns count

   return count
