Hi, I have a large text file I need to sort in Java. The format is: word [tab] frequency [new line] The algorithm for sorting is: Read some of the file, filtering for purlely alphabetic words. Once you have X number of alphabetic words, call Collections.sort and write the result to a file. Repeat until you have finished reading the f...
So I've made easy math programs with C before, but my task at hand is a bit complex for where my knowledge is at the moment. I need to take the calculator found here (calculator: http://ohts.wustl.edu/risk/calculator.html, appendix which covers it a bit: http://ohts.wustl.edu/risk/formula.html) and program it into a ObjC program. I'm ha...
Hi, in an assignment, I have designed a input validation loop in C#, and I would like it to be able to check for the correct input format. I'm not for sure, but I think my designed loop is not checking the type of input, just what char is entered. I know I could use a try-catch block, but shouldn't you only use exceptions for exceptio...

I have a question where there are four arrays, two for men and two for women. One of the men array is the age in increasing order and the other array is the height of men in increasing order. The two arrays for women are also the same. Now if one of the men marries a women, then form the age array, the men to the left of this man should...
I am implementing my own linked list in Java. The node class merely has a string field called "name" and a node called "link". Right now I have a test driver class that only inserts several names sequentially. Now, I am trying to write a sorting method to order the nodes alphabetically, but am having a bit of trouble with it. I found...

I am working on a program in C as a part of Homework in which I have to get the product of two long numbers which are taken as character string. eg: 123456789021 and 132456789098. Since it is taken as a string, I converted them to long long int for the multiplication. But the resulting product will be very large(larger than long long int...

Also, should the balance value be public in the header? Currently it is not, and it shows "error in this context" every time it's mentioned in this main code. [stackover...
Okay this is my code for deleting a node from a linked list. vec_store holds seq and size. Variable seq holds the vectors and a pointer. For some reason, the else if(i<s->size-1) doesn't work which is the last condition. Any1 can solve the problem? By the way this is C code. void delete_vec(vec_store s, int i) { if (i<0 || s->si...
