2^x mod n = 1 acm竞赛题 Give a number n, find the minimum x that satisfies 2^x mod n = 1. Input One positive integer on each line, the value of n. Output If the minimum x exists, print a line with 2^x mod n = 1. Print 2^? mod n = 1 otherwise. You should replace x and n with specific numbers. Sample Input 2 5 Sample Output 2^? mod 2 = 1 2^4 mod 5 = 1

The USB Multi-Interface driver is a replacement driver for the system provided Multi-Interface driver. This driver was developed to overcome some bugs that are included in the build in driver and to introduce new features. The driver is compatible to the system provided Multi-Interface driver. If the driver is installed on a system, it does not automatically replace the system provided driver. It exists parallel to the system driver and is assigned to a device during the installation process.

In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a seemingly inevitable drawback of undesired reflection exists in such cloaks. Here we suggest using high-order transformations to create smooth moduli at the outer boundary of the cloak, therefore completely eliminating the detrimental scattering within the limit of geometric optics. We apply this scheme to a non-magnetic cylindrical cloak and demonstrate that the scattered field is reduced substantially in a cloak with optimal quadratic transformation as compared to its linear counterpart.

program which uses hashing techniques for storing and retrieving the data. Input to the program: Some random numbers. Input will be from a file. Output: First the program reads all the input and store it properly using some hash techniques. Once your program reads the complete input,it waits for the user input (prompt to the user). User now enters some number.program displays if this number exists in the list or not. it also display the time taken in the search operation.
