Problem 4

A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules:

• The wanted word is in lowercase.
• The crowd of letters is all in uppercase.
• Note that the word will be spread out amongst the random letters, but their letters remain in the same order.

detectWord("UcUNFYGaFYFYGtNUH") // "cat"

detectWord("bEEFGBuFBRrHgUHlNFYaYr") // "burglar"

detectWord("YFemHUFBbezFBYzFBYLleGBYEFGBMENTment") // "embezzlement"
