please slove this question in c. don't copy other's code. thanks

Word A is considered a subsequence of another word B if A can be obtained by deleting 0 or more characters from string B. Given two words composed of lowercase and uppercase letters, can you check if A is a subsequence of B in a case-insensitive manner?

Requirements

  • Assume the input length for the two strings is no more than 1000 characters.
  • String library functions are NOT allowed.
  • Character handling functions such as tolower() are allowed.
  • Follow the format of the examples below.
  • The program will read two words, then print YES if the first word is a subsequence of the second word, and NO otherwise.

output:

Examples (your program must follow this format precisely)

Example #1

Enter first word: HeLlO
Enter second word: aaaaaaaaaaaaaahhhhhhhhhhhyyyyyyyyyyyyeeeeeeeelllllllllllkjjjjjjjjjjjooooopppppppp
