Let G be an undirected connected graph with distinct edge weight. Let emax be the edge with maximum weight and emin the edge with minimum weight. Which of the following statements is false?

The number of tokens in the following C statement is:

printf("i = %d, &i = %x",i, &i);

Comparing the time $$T1$$ taken for a single instruction on a pipelined $$CPU$$ with time $$T2$$ taken on a non-pipelined but identical $$CPU,$$ we can say that

An instruction pipeline has five stages where each stage takes $$2$$ nanoseconds and all instructions use all five stages. Branch instructions are not overlapped, i.e., the instruction after the branch is not fetched till the branch instruction is completed. Under ideal conditions.

(a) Calculate the average instruction execution time assuming that $$20$$% of all instruction executed are branch instructions. Ignore the fact that some branch instructions may be conditional.

(b) If a branch instruction is a conditional branch instruction, the branch need not be taken. If the branch is not taken, the following instructions can be overlapped. When $$80$$% of all branch instructions are conditional branch instructions, and $$50$$% of the conditional branch instructions are such that the branch is taken, calculate the average instruction execution time.
