   1 0 1 0 
  1 0 1 0 1 
  

📘 Explanation

This program combines two major phases to construct a complex binary diamond pattern using nested loops. Unlike focusing on row structures, the inner logic evaluates the expression j%2 to continuously alternate values horizontally.

The first main set of nested loops prints an inverted triangle structure where the rows decrease in size. The second set of nested loops handles the right-side-up triangle layout where rows progressively scale up. Both sections dynamically handle trailing column changes through space formatting.

🧠 Algorithm

1. Accept the input tracking value 'num' directly from the console interface.
2. Initialize the top half loop cycling backwards down to 1 to format the inverted section.
3. Distribute the leading offsets using inner loop restrictions tracking variables 'num' and 'i'.
4. Run an independent inner sequence printing j%2 to switch values from 1 to 0 sequentially.
5. Duplicate structural properties in the lower phase loop while flipping the outer loop control direction to iterate forward up to 'num'.
