In this task, you are given a natural language interpretation of commands (consist of logical operations) to select relevant rows from the given table. Your job is to generate command (in terms of logical operations) from given natural language interpretation. Define body (contains a collection of statements that define what the this logical operator does) of each logical operator between '{}' parenthesis. Here are the definitions of logical operators that you can use while generating command: 
 1. count: returns the number of rows in the view. 
 2. only: returns whether there is exactly one row in the view. 
 3. hop: returns the value under the header column of the row. 
 4. and: returns the boolean operation result of two arguments. 
 5. max/min/avg/sum: returns the max/min/average/sum of the values under the header column. 
 6. nth_max/nth_min: returns the n-th max/n-th min of the values under the header column. 
 7. argmax/argmin: returns the row with the max/min value in header column. 
 8. nth_argmax/nth_argmin: returns the row with the n-th max/min value in header column. 
 9. eq/not_eq: returns if the two arguments are equal. 
 10. round_eq: returns if the two arguments are roughly equal under certain tolerance. 
 11. greater/less: returns if the first argument is greater/less than the second argument. 
 12. diff: returns the difference between two arguments. 
 13. filter_eq/ filter_not_eq: returns the subview whose values under the header column is equal/not equal to the third argument. 
 14. filter_greater/filter_less: returns the subview whose values under the header column is greater/less than the third argument. 
 15. filter_greater_eq /filter_less_eq: returns the subview whose values under the header column is greater/less or equal than the third argument. 
 16. filter_all: returns the view itself for the case of describing the whole table 
 17. all_eq/not_eq: returns whether all the values under the header column are equal/not equal to the third argument. 
 18. all_greater/less: returns whether all the values under the header column are greater/less than the third argument. 
 19. all_greater_eq/less_eq: returns whether all the values under the header column are greater/less or equal to the third argument. 
 20. most_eq/not_eq: returns whether most of the values under the header column are equal/not equal to the third argument. 
 21. most_greater/less: returns whether most of the values under the header column are greater/less than the third argument. 
 22. most_greater_eq/less_eq: returns whether most of the values under the header column are greater/less or equal to the third argument.

Input: Consider Input: select the rows whose year of election record fuzzily matches to 1951 . take the candidates elected record of this row . select the rows whose year of election record fuzzily matches to 1948 . take the candidates elected record of this row . the first record is less than the second record .

Output: less { hop { filter_eq { all_rows ; year of election ; 1951 } ; candidates elected } ; hop { filter_eq { all_rows ; year of election ; 1948 } ; candidates elected } }


Input: Consider Input: select the rows whose country of release record fuzzily matches to argentina . there is only one such row in the table . the title record of this unqiue row is demasiado candente .

Output: and { only { filter_eq { all_rows ; country of release ; argentina } } ; eq { hop { filter_eq { all_rows ; country of release ; argentina } ; title } ; demasiado candente } }


Input: Consider Input: select the rows whose tournament record fuzzily matches to bc open . take the margin of victory record of this row . select the rows whose tournament record fuzzily matches to glen campbell - los angeles open . take the margin of victory record of this row . the first record is 3 larger than the second record . the margin of victory record of the first row is 5 strokes . the margin of victory record of the second row is 2 strokes .
Output: and { eq { diff { hop { filter_eq { all_rows ; tournament ; bc open } ; margin of victory } ; hop { filter_eq { all_rows ; tournament ; glen campbell - los angeles open } ; margin of victory } } ; 3 } ; and { eq { hop { filter_eq { all_rows ; tournament ; bc open } ; margin of victory } ; 5 strokes } ; eq { hop { filter_eq { all_rows ; tournament ; glen campbell - los angeles open } ; margin of victory } ; 2 strokes } } }
