当我们需要判断字符串S是否可以通过附加另一个字符串S1的子序列来获得时,我们可以使用以下的算法:
下面是Python的代码实现:
def can_get_by_appending_subsequence(S, S1):
i, j = 0, 0
while i < len(S) and j < len(S1):
if S[i] == S1[j]:
j += 1
i += 1
return j == len(S1)
S = "abcdefghi"
S1 = "adgi"
print(can_get_by_appending_subsequence(S, S1)) # True
S = "abcdefghi"
S1 = "adki"
print(can_get_by_appending_subsequence(S, S1)) # False
以上就是本文介绍的算法和代码。
