i changed it to be less vague

"Your task is to make a program which takes in a sentence and returns a string which shows the position
of each word in the sentence. If a word appears more than once in the sentence, your string should
return the position of the first occurrence of the word. Capitalisation of words should be accounted for:
'BEE' should be considered the same as 'bee'. The sentences include no punctuation."

Not a valid suggestion

Question is too vague
