Capitalize the First Letter

Take a fully lowercase word and capitalize only its first letter, leaving the rest unchanged. You are given a string named word set to "banana". Use Substring(0, 1) with ToUpper to get the capitalized first letter, then use Substring(1) to grab everything from the second character onward, and concatenate the two pieces. Substring with a single argument returns the rest of the string starting at that index. Print the combined result.
