We used indicator random variables in the proof of the expected running time of RANDOMIZED-QUICKSORT. For this problem, you should read about indicator variables and the hiring problem in Sections 5.1 and 5.2 of the textbook. As part of a cryptography assignment in CMSC 426, a student has written code to generate random permutations P on a set of n characters. If the permutation leaves too many inputs unchanged, it might result in a weakness in the system. Assuming the permutations are truly random, how many characters do I expect to be left unchanged by the permutation

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2

Which boolean operator enables you to exclude a search term? a} not b} and c} or d} plus

What did i do wrong with this const discord = require('discord.js'); var bot = new discord.client(); const token = 'ntm3mjcxmtu1mjg3ote2ntq2.dyogew.dpfiwfpuifzuzvifop-csuxasnm' const prefix = "! " bot.registry.registergroup('simple', 'simple'); bot.registry.registerdefaults(); bot.registry. + '/commands'); bot.on('message', message => { if(message.content == 'hi! ') { message.channel.send ('@everyone sup, how is @everyone day going'); } if(message.content == 'h3lp') { message.channel.send ('dose not have any commands yet'); } bot.on('ready', function() { console.log("ready") }); bot.login(token);
