Start with an infinite two dimensional grid filled with zeros, indexed from (1,1) at bottom left corner with coordinates increasing towards the top and right. Given a series of coordinate (r, c) where r is the ending row and c is the ending column, add 1 to each element in the range from (1,1) to (r, c) inclusive. Once all coordinates are processed, determine how many cells contain the maximal value in the grid.

Pthreads programming: create and terminate a thread write a c++ program that creates a thread. the main will display a message “hello world from the main”. the main will create a thread that will display a message “hello world from the thread” and then terminates with a call to pthread_exit()

Based on your knowledge of a good network, describe what you think is a perfect network would be. what kind of information and resources could users share on this network. what would the network administrator do? what kind of communication would be used?

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
