Logic:-

 Like reverse string, this is a reverse sentence. So first we are taking an input from the user after that we are finding the string or sentence last index point so we can reverse a sentence while reversing a sentence if any space occurs we take and space and print space after that again string starts printing. I  strongly prefer a program first try to understand this program so can understand the logic basically what is going on.
