i have written a program for creating an infix tree for the given expression.
the program is working fine if we give the expression completlely binded with operators and operands but when we ignore the brackets we need to consider the priority of the operators nad build the tree.
i am not getting the idea how to do that.
i have tried with a pen and paper but my efforts are in vain.
any suggestions on how can i change my program so that it works for both the inputs.
Is it possible to combine a regular expression with a aritmetical expression? For example, taking a 8-numbers caracter sequece and casting each output of a grep, comparing to a constant.
THX! (2 Replies)

I am unable to find files, those are present anywhere in the same directory tree, based on the creation date. I need to find the files with their path, as I need to create them in another location and move them. I need some help with a script that may do the job.
