Live coding, with 15 min time limit: A precedence rule is given as "P>E", which means that letter "P" is followed directly by the letter "E". Write a function, given an array of precedence rules, that finds the word represented by the given rules. Note: Each represented word contains a set of unique characters, i.e. the word does not contain duplicate letters. Examples: findWord(["P>E","E>R","R>U"]) // PERU findWord(["I>N","A>I","P>A","S>P"]) // SPAIN Test cases: findWord(["U>N", "G>A", "R>Y", "H>U", "N>G", "A>R"]) // HUNGARY findWord(["I>F", "W>I", "S>W", "F>T"]) // SWIFT findWord(["R>T", "A>L", "P>O", "O>R", "G>A", "T>U", "U>G"]) // PORTUGAL findWord(["W>I", "R>L", "T>Z", "Z>E", "S>W", "E>R", "L>A", "A>N", "N>D", "I>T"]) // SWITZERLAND
