Each row consists of the node tuples that are adjacent to that particular vertex along with the length of that edge. For example, the 6th row has 6 as the first entry indicating that this row corresponds to the vertex labeled 6. The next entry of this row "141,8200" indicates that there is an edge between vertex 6 and vertex 141 that has length 8200. The rest of the pairs of this…
Which of the following solutions is most likely to correctly perform data flow analysis for the "FLOAT_ABS" p-code operator when it is correctly integrated into the script? Question 15 options: Simply adding PcodeOp.FLOAT_ABS into the "unary_operators" list. Simply adding PcodeOp.FLOAT_ABS into the "binary_operators" list. Ignore PcodeOp.FLOAT_ABS since it does not introduce data flow from the input to the output. None of above.
