Please solve the Python problem. It's hard

The company regularly conducts medical checkups for employees every year to measure blood pressure, and the blood pressure levels include systolic blood pressure (high) and diastolic blood pressure (low). The company measures two blood pressure values for all employees and calculates and outputs the mean and median values of all employees' systolic and diastolic blood pressure.

The center value of a numeric string is the value that the numbers are centered in order. For example, 3,7,1,9,5 has a median of 5 The median values of 5, 8, 2, and 6 are the average values of 5 and 6. (Round from decimal point unconditionally).

Help complete the split - range() function to complete the median calculation for both blood pressure in the employee. (Note: This program does not use sorting to find the median.)

Input format:

n: Number of employees ha1, …, han: systolic blood pressure in the staff hb1, …, hbn: diastolic blood pressure in staff

Output type: ha_avg : Employee average systolic blood pressure hb_avg : Employee average diastolic blood pressure ha_md : median systolic blood pressure in the employee hb_md : median diastolic blood pressure of the employee

Conditions def split_range (pivot_position, mid, left, right): Function

pivot_position: split point position

mid: intermediate position

left: align left end

right: align right end

This function gradually narrows the search based on the result of calling the split function (pivot_position).

What code should I write in the middle question mark? crying Please answer the question If you can, please interpret it Thank you as always!
