 Exercise L9.E2

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.

Criteria:

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

                  a. One  ‘S’ molecule and,

                  b. Four ‘O’ molecules and,

                  c. One ‘Na’ molecule 

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

                  a. One  ‘S’ molecule and,

                  b. Three ‘O’ molecules and,

                  c. One ‘Mg’ molecule 

       3.The chemical is categorized as ‘Level_3’ if the contaminant contains;

                  a. Two  ‘O’ molecules and,

                  b. Three ‘Cl’ molecules 

        4. If any contaminant belongs to more than one category above then the chemical is  categorized as ‘Level_4’.

        5.If the contaminant doesn’t belong to any of the above categories then the chemical is categorized as ‘Level_0.txt’.

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'
The leftover molecules cannot form Level_2.
