You are given a text file called "master" that is structured this way: the first line contains a string which is the name of a file to be created. Subsequent lines are the names of other text files whose contents are to be copied into the new file, in the order that they appear. So, if master's contents were: bigfile
alist
blist
clist
then bigfile will contain the contents of alist, and tacked on to that will be the contents of blist followed by the contents of clist.

When finished, make sure that the data written to the new files have been flushed from their buffers and that any system resources used during the course of running your code have been released.(Do not concern yourself with any possible exceptions here-- assume they are handled elsewhere.)

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
