Final answer:
To determine whether each subsequence is contiguous or not, we need to check if it is a consecutive part of the corresponding sequence.
Step-by-step explanation:
Given the subsequences w and the sequences a, we need to determine whether each subsequence is a contiguous subsequence of the corresponding sequence.
a. s = {1,2,3,4,5,6}
The subsequence w = {1,2,3,4,5,6} is a contiguous subsequence of s because it is a consecutive part of the sequence.
b. s = {1,2,3,4}
The subsequence w = {1,2,3,4,5,6} is not a contiguous subsequence of s because it is not a consecutive part of the sequence.
c. s = {1,2}
The subsequence w = {1,2,3,4} is not a contiguous subsequence of s because it is not a consecutive part of the sequence.
d. s = {1,2,3}
The subsequence w = {1,2,3,4,5,6} is not a contiguous subsequence of s because it is not a consecutive part of the sequence.
