      Pehle mujhe bhi yahi laga tha but this ques is different
      We can post a letter in any of the 4 letter box meaning for each letter we have 4 different ways
      We can put multiple letters in a single letter box also (like we do it in real life)
      Toh har letter ko post krne ke liye 4 ways hai toh ans 4 ki power 5
