Output multiple diamond maps and write them again!

/**
* Multiple diamond shapes are output.
* Idea:
* 1. Define the three parameters "row", "COLUN", and "M", which respectively represent the displayed number of rows, number of columns, and number of rows in the upper triangle;
* 2. Use for loop nesting
* 2. print the number of lines displayed on the outermost layer;
* 3. The second layer controls the number of rows in the upper and lower triangles of the diamond;
* 4. The third layer controls the number of columns displayed on each line.
