QuestionHint and solution stay closed until you open them
Read one word (letters only, no spaces). Print the word reversed.
A C string ends with a null byte. Reverse the characters before that null, then print with %s.
Input. One word of at most 32 characters.
Output. The reversed word.
Constraints
- 1 ≤ length ≤ 32
- The word contains no spaces.

Hint
- scanf("%31s", word) reads a word. strlen(word) is the length.
- Swap word[i] with word[len - 1 - i] for i from 0 to len/2 - 1.
