Hi, I solved the Leetcode problem 392.

It's about comparing two strings.

s should be a subsequence of t, and we have to consider the order,

but the characters in s can appear separately within t.

To summarize, it's just about checking if s is a subsequence.

Please read the description.

 

Why is the first example 'true'?

It's because s is a subsequence of t,

even if the characters are not contiguous.

However, in Example 2,

the output is false

because there is no 'x'."

 

here is my solution

 

I just need to check if the factor of s consists of t or not.

So, I used the for loop and lf statement for comparing the both of factors.

and declared a variable outside the for loop, because for processing the for loop statement, the variable should be changed. 

Then, I plan to use a ternary operator in the return part.
