  Given two strings s and t, determine if they are both one edit distance apart.
  
  Note: 
  
  There are 3 possiblities to satisify one edit distance apart:
  
  Insert a character into s to get t
  Delete a character from s to get t
  Replace a character of s to get t
  Example 1:
  
  Input: s = "ab", t = "acb"
  Output: true
  Explanation: We can insert 'c' into s to get t.
  Example 2:
  
  Input: s = "cab", t = "ad"
  Output: false
  Explanation: We cannot get t from s by only one step.
  Example 3:
  
  Input: s = "1203", t = "1213"
  Output: true
  Explanation: We can replace '0' with '1' to get t.
