Modular Program Structure. Analysis of Structured Programming Examples. Ways to Reduce Coupling. Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsin⁡x Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.
