Reverse words in a sentence?

Short answer: string input = "I love dotnet"; string[] words = input.Split(' '); Array.Reverse(words); string result = string.Join(" ", words);

Example code

string input = "I love dotnet";
string[] words = input.Split(' '); Array.Reverse(words); string result = string.Join(" ", words);

Real-world example (ShopNest)

In coding rounds, state complexity aloud, write a clear ShopNest-flavored example (orders, carts), then handle edge cases (empty list, null, overflow).

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
