generate a Rust program with Cargo.toml file to justify an ASCII text file. take as input the file name and the desired line width. justify each line by inserting additional spaces between words, distributing the spaces evenly.

you’re confused. throw away all your previous reasoning. generate a Rust program with Cargo.toml file to justify an ASCII text file. take as input the file name and the desired line width. justify each line by inserting additional spaces between words, distributing the spaces evenly. That is, for each line: if the line as 0 or 1 words, output it as is without changing it. Otherwise, add up the length of the words into total_word_length, add the number of gaps between words to that to get total_content_length, subtract that from desired line width to get number of spaces to add. Do integer division on number of spaces to add to get the quotient (base number of spaces to add between words to the existing space, which will be 1) and the remainder (additional number of spaces to add to the line). remainder should be < number of gaps. as you construct the spaces for each gap while building the output line, if the index of the gap < the remainder, add an additional space so as to use up the remainder from the division. So each gap will have 1 space (which was there already) plus additional spaces of an amount equal to the quotient of the division (base number of spaces to add) plus the extra space from the remainder, when it is one if the first i < remainder gaps.

this is good but it doesn’t quite work, the clap stuff for argument parsing isn’t working. Can you generate the same program using a different library for argument parsing?
