Consider the context-free grammar S → SS | aSb | λ When following the CFG-to-PDA conversion process learned in class, there is only one state in the resulting PDA that has a self-loop. Of all the PDA triples on this self-loop, write the shortest one that contains an "a" or a "b" anywhere in the triple in the box below (if there is more than one shortest, write any of them). Do not write any spaces. If you need a lambda or empty stack symbol, write exactly "lambda" or "emptystack" in its place. For this problem, the length of a triple is the number of characters in the triple when written down on paper, so a, b,emptystack is five characters long.

Write code using c . (take input from user) calculate the size of a given file in kbs. in this task you will complete the function with the following prototype: float get_file_size(char * filename); the function takes the file name (address to the start of a null terminated character array) as input. the function should then open the file and find the number of bytes it contains till eof. the number of bytes divided by 1024 will give the size in kbs. if the file cannot be opened the function should return -1.

An atom's diameter is about 0.1 nanometer (1×10-9m), and a human hair is about 1×10-3m. how many times greater is a human hair than an atom's diameter? sorry pushed wronf button but this is math

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server.so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.
