Meow is playing a game with her friend. She gives her friend a string s and asks her whether another string t “hides" inside s. Let's be a bit more precise about hiding. Say you have two strings s and t. The string t hides inside s if all the letters of t appear in s in the order that they originally appear in t. be additional letters between the letters of s, interleaving with them. There may Under this definition, every string hides inside itself: 'cat'hides inside 'cat'. For a more interesting example, the string 'cat' hides inside the string 'afciurfdasctxz' as the diagram below highlight the letters of'cat': afciurfdasctxz. Importantly, these letters must appear in the order they originally appear. Hence, this means that 'cat' does not hide inside the string 'xaytpc'. In this case, although the letters c, a, and t individu- ally appear, they don't appear in the correct order. As another example, the string 'moo' does not hide inside 'mow'. This is because although we can find an m and an o, the second o doesn't appear in 'mow'. However, finding whether a string hides in another should ignore the case of the characters in those strings. For example, 'cat' hides in 'Cat ', and similarly 'Cat' also hides in 'cat'. In this problem, you'll help Meow's friend by implementing a function is_hidden(s, t) that deter- mines whether t hides inside s. The function returns a Boolean value: True if t hides inside s and False otherwise. Here are some more examples: is_hidden("welcometothehotelcalifornia","melon") True False is_hidden("welcometothehotelcalifornia","space") is_hidden("TQ89MnQU3IC7t6", "MUIC") -- -- True ==
