As Sherlock Holmes was investigating a crime, he identified n suspects. He knows for sure that exactly one of them committed the crime. To find out which one did it, the detective lines up the suspects and numbered them from 1 to n. After that, he asked each one: "Which one committed the crime?". Suspect number i answered either "The crime was committed by suspect number ai", or "Suspect number aididn't commit the crime". Also, the suspect could say so about himself (ai = i).
Sherlock Holmes understood for sure that exactly m answers were the truth and all other answers were a lie. Now help him understand this: which suspect lied and which one told the truth?
Input
The first line contains two integers n and m (1 ≤ n ≤ 105, 0 ≤ m ≤ n) — the total number of suspects and the number of suspects who told the truth. Next n lines contain the suspects' answers. The i-th line contains either "+ai"(without the quotes), if the suspect number isays that the crime was committed by suspect number ai, or "-ai"(without the quotes), if the suspect number i says that the suspect number ai didn't commit the crime (ai is an integer, 1 ≤ ai ≤ n).
It is guaranteed that at least one suspect exists, such that if he committed the crime, then exactly m people told the truth.
Output
Print n lines. Line number i should contain "Truth"if suspect number i has told the truth for sure. Print "Lie"if the suspect number ilied for sure and print "Not defined"if he could lie and could tell the truth, too, depending on who committed the crime.
