Consider the following code sequence having five instructions I1to I5. Each of these instructions has the following format. OPRi, Rj, Rk where operation OP is performed on contents of registers Rj and Rk and the result is stored in register Ri. I1:ADDR1, R2, R3 I2:MULR7, R1, R3 I3:SUBR4, R1, R5 I4:ADDR3, R2, R4 I5:MULR7, R8, R9 Consider the following three statements. S1: There is a nanti-dependence between instructions I2and I5 S2: There is a nanti-dependence between instructions I2 and I4 S3:With in an instruction pipeline a nanti-dependence always creates one or more stalls Which one of above statements is / are correct?
What will be the output of the following Python code snippet?
Consider a set U of 23 different compounds in a Chemistry lab. There is a subset S of U of 9 compounds, each of which reacts with exactly 3 compounds of U. Consider the following statements:
I. Each compound in U S reacts with an odd number of compounds.
II. At least one compound in U S reacts with an odd number of compounds.
III. Each compound in U S reacts with an even number of compounds.
Which one of the above statements is ALWAYS TRUE?
