Scott, I think you missed the original request. The Original request is to stop reading the file once the program finds a key greater than the desired key. For example if the input has 300 million records and it is sorted , then if the desired key is found in the first 2 million records, then there is no need to read the other 298 million records. Reading the file twice is NOT an optimal solution.
