Complete the following table, which shows the mapping of Java source codes to the corresponding bytecode line numbers. Bytecode Lines (Start - End] Java Source Code (b*b) (4 * a *c) sart = Math.sqrt((b* b)-(4 a* c)); (-b + sqrt) firstRoot = (-b + sart) / (2 * a): (-b - sqrt) secondRoot = (-b - sqrt) / (2 * a): return 0; Note: You don't need to write the bytecode, just mention the starting and ending line numbers in the table above.
