title: Check if string contains the substring's sequence of characters in order, but not necessarily right next to each other
body: <p>Given two strings, return true if the first string contains the second string's sequence of characters in order, but not necessarily right next to each other. </p>
  
  <p>For example,  String : "I am hungry and want food right now", Substring: "mto". The substring where o comes before t in the sentence does not count, they have to be in order but not necessarily right next to each other.</p>
  
  <p>I'm not really looking for code, just in general how would you solve this problem!</p>
