Odd Word Reversal

Easy
string array
Problem Description

Given a sentence, reverse only the words at odd indices (1-indexed). Words are separated by spaces.

Input Format
A single line containing a sentence with words separated by spaces.
Output Format
The sentence with words at odd positions (1st, 3rd, 5th, etc.) reversed.
Constraints
1 <= sentence length <= 1000

Words contain only alphabetic characters

1 <= number of words <= 100
Sample Input/Output
Input: 
I love solving coding problems
Output: 
I evol solving gnidoc problems
Explanation

Words at positions 1, 3, 5 are: "I", "solving", "problems" (unchanged). Words at positions 2, 4 are: "love" → "evol", "coding" → "gnidoc".

Solution Hints
  • Read carefully: Understand input/output format and constraints
  • Start simple: Think of brute force solution first, then optimize
  • Edge cases: Consider empty inputs, single elements, max constraints
  • Data structures: Choose arrays, hash maps, sets based on problem needs
  • Time complexity: Ensure your solution fits within time limits
  • Test examples: Verify logic with provided sample inputs
