In a given sentence or an array of characters, reverse the order of words.
Question
In a given sentence or an array of characters, reverse the order of words.
Solution
Sure, here is a step-by-step guide on how to reverse the order of words in a given sentence or an array of characters in Python:
- First, you need to split the sentence into words. In Python, you can use the
split()function to do this. This function splits a string into a list where each word is a list item. For example:
sentence = "Hello World"
words = sentence.split()
print(words)
This will output: ['Hello', 'World']
- Next, you need to reverse the order of the words. You can use the
reverse()function in Python to reverse the order of items in a list. For example:
words.reverse()
print(words)
This will output: ['World', 'Hello']
- Finally, you need to join the words back into a sentence. You can use the
join()function in Python to do this. This function takes all items in an iterable and joins them into one string. A string must be specified as the separator. For example:
reversed_sentence = ' '.join(words)
print(reversed_sentence)
This will output: 'World Hello'
So, to put it all together, here is a function that takes a sentence as input and returns the sentence with the order of words reversed:
def reverse_words(sentence):
words = sentence.split()
words.reverse()
reversed_sentence = ' '.join(words)
return reversed_sentence
You can use this function like this:
print(reverse_words("Hello World"))
This will output: 'World Hello'

Given an input string s, reverse the order of the words.A word is defined as a sequence of non-space characters. The words in s will be separated by at least one space.Return a string of the words in reverse order concatenated by a single space.Note that s may contain leading or trailing spaces or multiple spaces between two words. The returned string should only have a single space separating the words. Do not include any extra spaces. Example 1:Input: s = "the sky is blue"Output: "blue is sky the"Example 2:Input: s = " hello world "Output: "world hello"Explanation: Your reversed string should not contain leading or trailing spaces.Example 3:Input: s = "a good example"Output: "example good a"Explanation: You need to reduce multiple spaces between two words to a single space in the reversed string. Constraints:1 <= s.length <= 104s contains English letters (upper-case and lower-case), digits, and spaces ' '.There is at least one word in s. Follow-up: If the string data type is mutable in your language, can you solve it in-place with O(1) extra space?
