Read the stock price data of Alphabet Inc. (GOOG) for the time period between April 01, 2020 and October 01, 2020 in the file 'alphabet.csv' into a Pandas DataFrame. You can download it from Blackboard in session 12. (1) Convert the “Date” column into Datetime format and assign it as the index column. And output the DataFram containing data for month x. (2) Calculate the net increase of stock price for each day and append them as a new column “Net Increase” to the DataFrame using the closing price minus the opening price. And output the DataFram containing data for month x. (3) Find the day that has the highest opening price, and calculate the mean of closing price for all days.

You are to write a lexical analyzer/scanner for the language decaf in java. Goals: 1. The input of the scanner is a source code file and the output of the scanner is a stream of tokens. 2. Your scanner should go for longest possible match i.e. a string ‘:=’is to be identified as ‘ass-symbol’ and not as ‘:’and ‘=’. 3. Token is represented as (Kind, Value). We use the following symbols to denote different kinds of tokens KEY denotes reserved words SYM denotes special symbols ID denotes identifiers NUM denotes numeric constants STR denotes string constants 4. Check lexical errors: giving meaning error messages and the lines where errors occur. The kinds of lexical errors are: - Illegal character, that is, scanner may recognize a character that is not in the alphabet of TINY+ - The right bracket of a STRING is lost - The right delimiter of a comment is lost

Here's a sample code for a lexical analyzer/scanner for the decaf language in Java: import java.io.*; import java.util.*; public class Scanner { private BufferedReader br; private char ...

To rotate a letter (lowercase) means to shift it through the alphabet, wrapping around to the beginning if necessary, so ‘a’ rotated by 3 is ‘d’ and ‘a’ rotated by -1 is ‘z’. To rotate a word (all letters are lowercase), rotate each letter by the same amount. For example, “cheer” rotated by 7 is “jolly” and “melon” rotated by -10 is “cubed”. You might want to use the built-in function ord, which converts a character to a integer code, and chr, which converts integer codes to characters. Letters of the alphabet are encoded in alphabetical order, so for example: ord('c') - ord('a') == 2. Because 'c' is the two-eth letter of the alphabet. Input A string and an integer. Output A new string.

It then loops through each letter in the word, calculates the new letter by adding the rotation to the original letter's position in the alphabet, and then converts the new position back to a letter ...

Each letter in the alphabet can be given a value based on its position in the alphabet, A being 1 throughto Z being 26. Two letters can produce a third letter by adding together their values, deducting 26 fromthe sum if it is greater than 26, and finding the letter whose value equals this result.A simple encryption scheme for a string is as follows. Working from left to right, after leaving the left-most character alone, each character is replaced with the character produced by adding it to thecharacter to its immediate left.For example:• The string ENCRYPT goes through the steps ENCRYPT → ESCRYPT → ESVRYPT → ESVNYPT →ESVNMPT -> ESVNMCT -> ESVNMCW1(a) [ 24 marks ]Write a program that reads in an encrypted string, between 1 and 10 uppercaseletters inclusive, and outputs the original version of that string

The formula subtracts the code of the previous character from the current code, and takes the result modulo 26 (to handle cases where the sum is greater than 26). The main program reads the input ...

7-3 Score Processing 分数 10 作者翁恺单位浙江大学 Write a program to process students score data. The input of your program has lines of text, in one of the two formats: Student's name and student id, as <student id>, <name>, and Score for one student of one course, as <student id>, <course name>, <marks>. Example of the two formats are: 3190101234, Zhang San 3190101111, Linear Algebra, 89.5 Comma is used as the seperator of each field, and will never be in any of the fields. Notice that there are more than one word for name of the person and name of the course. To make your code easier, the score can be treated as double. The number of the students and the number of the courses are not known at the beginning. The number of lines are not known at the beginning either. The lines of different format appear in no order. One student may not get enrolled in every course. Your program should read every line in and print out a table of summary in .csv format. The first line of the output is the table head, consists fields like this: student id, name, <course name 1>, <course name 2>, ..., average where the course names are all the courses read, in alphabet order. There should be one space after each comma. Then each line of the output is data for one student, in the ascended order of their student id, with score of each course, like: 3190101234, Zhang San, 85.0, , 89.5, , , 87.3 For the course that hasn't been enrolled, leave a blank before the comma, and should not get included in the average. The average has one decimal place. There should be one space after each comma. And the last line of the output is a summary line for average score of every course, like: , , 76.2, 87.4, , , 76.8 All the number output, including the averages have one decimal place. Input Format As described in the text above. Output Format As described in the text above. The standard output is generated by a program compiled by gcc, that the round of the first decimal place is in the "gcc way". Sample Input 3180111435, Operating System, 34.5 3180111430, Linear Algebra, 80 3180111435, Jessie Zhao 3180111430, Zhiwen Yang 3180111430, Computer Architecture, 46.5 3180111434, Linear Algebra, 61.5 3180111434, Anna Teng Sample Output student id, name, Computer Architecture, Linear Algebra, Operating System, average 3180111430, Zhiwen Yang, 46.5, 80.0, , 63.2 3180111434, Anna Teng, , 61.5, , 61.5 3180111435, Jessie Zhao, , , 34.5, 34.5 , , 46.5, 70.8, 34.

You are required to write a C program to: • Initialize GPIO peripherals • Initialise UART peripheral for receiving ASCII characters ‘A’ to ‘Z’ at baud 9600 • Initialise an internal array to hold 10 characters with head and tail: CharBuff • Repeat the following:o When data is received on the serial communication port, read ASCII character X, o If received character X is a capital letter add it to CharBuff, else ignore. o While CharBuff is not empty, transmit the morse code of the oldest stored character by blinking the LED (code provided for you). o When CharBuff is full, disable UART RX. o If UART RX is disabled, pushing the button P_B1 will activate it; otherwise, pushing the button does not affect your programme. You are recommended to use interrupt to control UART receiving data and coordinate the operation between CharBuff and P_LD2. 在我的代码基础上完成以上任务#include #include <gpio.h> #include "delay.h" #include "uart.h" #include <stm32f4xx.h> /* NOTE******** YOU CAN USE THE IN-UILT FUNCTION delay_ms(HOW_LONG) TO CAUSE A DELAY OF HOW_LONG MILLI SECONDS

A channel with alphabet $\{0,1,2,3,4\}$ has transition probabilities of the form $$ \mathrm{p}(\mathrm{y} \mid \mathrm{x})=\left\{\begin{array}{c} \frac{1}{2} \text { if } y=(x \pm 6) \bmod 5 \\ 0, \text { otherwise } \end{array}\right. $$ Compute the capacity of this channel in bits.

To compute the capacity of this channel, we need to first find the input distribution that maximizes the mutual information. Since the channel is memoryless, the input distribution that maximizes the ...

这段代码看起来是一个 Vue.js 组件中的 mounted 钩子函数。...最后，它还获取了一个字母表，并将其存储在组件的 alphabet 属性中。最后，它调用了 getLocation() 方法，可能是为了获取用户的地理位置信息。
