Define a function `count_words` that, given an input string, return a hash whose keys are words in the string and whose values are the number of times each word appears: "to be or not to be" # => {"to"=> 2, "be"=> 2, "or"=> 1, "not"=> 1} your solution shouldn't use for-loops, but iterators like `each` are permitted. as before, nonwords and case should be ignored. a word is defined as a string of characters between word boundaries.

Aletter or menu command that starts an action when the user presses the designated letter and the alt key together is called what?

Alook-up table used to convert pixel values to output values on a monitor. essentially, all pixels with a value of 190 or above are shown as white (i.e. 255), and all values with a value of 63 or less are shown as black (i.e. 0). in between the pixels are scaled so that a pixel with a value p is converted to a pixel of value 2/127 −+3969). if a pixel has a value of 170 originally, what value will be used to display the pixel on the monitor? if a value of 110 is used to display the pixel on the monitor, what was the original value of the pixel?

Usually, when we sniff packets, we are only interested certain types of packets. we can do that by setting filters in sniffing. scapy’s filter use the bpf (berkeley packet filter) syntax; you can find the bpf manual from the internet. set the following filters and demonstrate your sniffer program again (each filter should be set separately): (a) capture only the icmp packet. (b) capture any tcp packet that comes from a particular ip and with a destination port number 23. (c) capture packets comes from or to go to a particular subnet. you can pick any subnet, such as 128.230.0.0/16; you should not pick the subnet that your vm is attached to.
