1) write a program using arduino or the development board that measures gravitational acceleration in 3-axes and displays the values on the LCD screen.

The program will do the following:

a) To be run upon initialization (i.e. implement this in the setup() function)

• Initialize the development board

• Sound the buzzer

• Write the message “ACCELEROMETER” on the LCD screen.

• Wait two seconds

• Sound the buzzer

A data compression software utilities various steps to compress a string of data one of the steps involves find the count of the character that are not repeated in the string

write a program that will find the day of the week from a date and will also prepare a calendar on a monthly basis. (Science: day of the week). July 20, 1973 is a FRIDAY using Zeller’s congruence is an algorithm developed by Christian Zeller

h=(q+[26(m+1)/10] + y +[y/4] + 6 * [y/100]+[y/400]) % 7

Where,

■ h is the day of the week (0: Saturday, 1: Sunday, 2: Monday.....)

■ q is the day of the month

■ m is the month (3: March, 4: April, ….., 12: December)

■ y is the year

NOTE: In this algorithm, January and February are counted as months 13 and 14 of the previous year. E.g. if it is February 2, 2010, the algorithm counts the date as the second day of the fourteenth month of 2009 (02/14/2009 in DD/MM/YYYY format). Consequently, for January and February, the year y should be replaced by y – 1. Suffice to say, the month m should also be replaced by m + 12 then.

Sample Input/Output :

Input: Enter year: 2005 Enter month (1-12): 1 Enter day: 21

Output: January 21, 2005 is FRIDAY

Instructions:

1. Input a 3-digit integer.
2. Print the largest digit in the integer.
3. Tip #1: Use % 10 to get the rightmost digit. For example, if you do 412 % 10, then the result would be the rightmost digit, which is 2.
4. Tip #2: On the other hand, use / 10 to remove the rightmost digit. For example, if you do 412 / 10, then the result would be 41.
5. Tip #3: You'd have to repeat Tip #1 and Tip #2 three times for this problem because the input is a 3-digit integer.

Input

1. A three-digit integer

Output

The first line will contain a message prompt to input the 3-digit integer.

The last line contains the largest digit of the inputted integer.

Enter a 3-digit integer: 173
Largest = 7

Enter a 3-digit integer: 109
Largest = 9

Enter a 3-digit integer: 666
Largest = 6

Instructions:

1. Input four float numbers; they could be positive or negative.
2. Only add all inputted negative numbers, and print its sum, up to 2 decimal place.
3. Hint: The previous/latest topic is about if-else-elseif statements, but do we need one here?

Input

1. First decimal number

2. Second decimal number

3. Third decimal number

4. Fourth decimal number

Output

The first four lines will contain message prompts to input the four decimal numbers.

The last line contains the sum of all the inputted negative numbers, with 2 decimal places.

Enter the first number: -30.22
Enter the second number: 10.5
Enter the third number: -2.2
Enter the fourth number: -1.8
Sum of all negatives = -34.22

Enter the first number: 50.23
Enter the second number: 100.23
Enter the third number: -123.4
Enter the fourth number: 0.0
Sum of all negatives = -123.40

Instructions:

1. Input three integers.
2. Print the integers in ascending order using your knowledge on conditional statements.

Input

1. First integer

2. Second integer

3. Third integer

Output

The first three lines will contain message prompts to input the 3 integers.

The last line contains the three integers in ascending order.

Enter the first integer: 6
Enter the second integer: 1
Enter the third integer: 3
1 3 6

write a program which takes the input from these arrays and decides the maximum runs that your favourite player has to score so far in order to get the orange cap. [The orange cap is awarded to the person who scores maximum runs in the tournament]. Also, please find out the maximum strike rate achieved by a batsman so far. Note: In total you are given 8 arrays represent the runs scored and the next 4 represent the total number of balls faced.

Sample Run:

Input:

[10, 45, 500, 400, 45, 56, 67, 78, 100, 8, 11]

[100, 450, 510, 410, 415, 56, 68, 87, 101, 9, 9]

[404, 445, 520, 450, 415, 156, 167, 488, 110, 4, 2]

[505, 445, 554, 410, 445, 556, 167, 178, 70, 4, 1]

[20, 100, 500, 345, 45, 65, 86, 69, 100, 7, 10]

[101, 246, 500, 355, 145, 165, 45, 45, 54, 8, 9]

[434, 456, 550, 395, 445, 165, 96, 369, 100, 4, 6]

[520, 340, 500, 405, 345, 565, 186, 169, 67, 3, 2]

Output:

Maximum Runs Scored: 556

Maximum Strike Rate: 286.206897​
