#Write python function, sms_encoding() which accepts a sentence and converts it into an abbreviated sentence to be sent as SMS and returns the abbreviated sentence. 

#Rules are as follows: 
#a. Spaces are to be retained as is 
#b. Each word should be encoded separately

#If a word has only vowels then retain the word as is
#If a word has a consonant (at least 1) then retain only those consonants

#Note: Assume that the sentence would begin with a word and there will be only a single space between the words.

#Sample Input	Expected Output
#I love Python	I lv Pythn
#MSD says I love cricket and tennis too	MSD sys I lv crckt nd tnns t
#I will not repeat mistakes	I wll nt rpt mstks
