You are provided with a file named contamination_analysis.txt. This file contains details regarding a contamination analysis ( The process of finding unwanted chemical compounds in a certain material) carried out for a set of chemicals by a lab. 

A set of chemical names and the molecular structure of the contaminant in each chemical is given in the file. 

Example input file (contamination_analysis.txt) :

ABC/D/12    C6-H5-Cl3-Na
DE/W/45     C7-S-O4-Na
MLI/85/9    C6-H6-S-O3-Mg
QT/36/X     C4-Cl3-O3-Cl3-O2
AL/2T/B     C2-N-H4-Na
PP/L2/28    C6-S-O8-Na-H2-Cl3

• Each line of the input file has a chemical name and the molecular formula of the contaminant found in the chemical ( ABC/D/12 is the chemical name, and C6-H5-Cl3-Na is the molecular formula for the contaminant in the chemical ABC/D/12 ).

• The number of chemicals in an input file can vary. The example input file has details regarding 6 chemicals but the input files in test cases can have up to 10 chemicals in a file.

You need to categorize each chemical in the input files based on the contaminant  in the chemical. The following criteria should be followed for categorizing chemicals.

1. The chemical is categorized as ‘Level_1’ if the contaminant contains;

1. The chemical is categorized as ‘Level_2’ if the contaminant contains;

Note : When categorizing, give priority to the order of the criteria.

Ex: If the contaminant has (C6-S-O3-Na-O2-Mg)

• One ‘S’
• Six ‘C’ s
• Five ‘O’ s
• One ‘Na’
• One ‘Mg’

Then the category is Level_1. Because after we categorized it to Level_1 the left molecules are

• Six ‘C’ s
• One ‘O’
• One ‘Mg'
