Answer:

List1=[['Physics','Quantum Physics','Theory of Relativity'],['Geometry', 'Plane Geometry', 'Coordinate Geometry']]

i=0

k=0

for i in range(0,2):

print("Category:"+List1[i][0])

for k in range(1,3):

print("\t"+List1[i][k])

Explanation:

The program required is mentioned above. And it has limitations, but is good enough to explain the fundamentals required.

Write a method called fact that recursively calculates the factorial value of its single int parameter. The value returned by fa

andrey2020 [161]

Answer:

The program to this question can be given as follows:

Program:

//class

public class factorial //defining class

{

//method fact

public static long fact(int x1) //defining method fact

{

//conditional statement

if (x1 <= 1) //if block checks parameter value less then equal to 1

{

return 1; //return value

}

else //else part

{

return (fact(x1 - 1) * (long) x1); //return factors using recursive function

}

//method main

public static void main(String[] args) //defining main method

{

long data=fact(5);//defining variable that holds function value

System.out.println("Factorial is: "+data); //print value

}

Output:

Factorial is: 120

Explanation:

In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.

If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.

In else part, it uses a recursive function to calculate factorial of a number and return its value.
Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.

One tool of Lean that is a container, card, or visual limit that signals when work needs to be done or replenishment needs to be

valentina_108 [34]

Answer:

Kanban System

Explanation:

Kanban can be regarded as one of Lean tools which is been designed to carry out reduction of the idle time in a production process. The idea or concept behind this Kanban system, is to make delivery of needs of the process needs at exactly the it needs it. Kanban can be reffered to as visual cards. Kanban can as well be explained as scheduling system that is used for lean manufacturing as well as just-in-time manufacturing. Taiichi Ohno, who was an industrial engineer at Toyota carried out development of kanban so that there could be an improved manufacturing efficiency. Kanban is considered as one method used to achieve JIT.

It should be noted that Kanban System is One tool of Lean that is a container, card, or visual limit that signals when work needs to be done or replenishment needs to be initiated .

Write a function called sum_scores. It should take four arguments, where each argument is the team's score for that quarter. It

saw5 [17]

Answer:

Here is the Python program which has a function sum_scores:

def sum_scores(score1, score2, score3, score4):

sum = score1 + score2 + score3 + score4

print(sum)

sum_scores(14,7,3,0)

Explanation:

Method sum_scores takes four arguments, score1, score2, score3, score4.
The sum variable adds these four scores and stores the value of their addition.
Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
The output of the above program is:
24
If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
The program along with the output is attached as a screenshot.

Assume that k corresponds to register $s0, n corresponds to register $s2 and the base of the array v is in $s1. What is the MIPS

BlackZzzverrR [31]

Answer:

hello your question lacks the C segment so here is the C segment

while ( k<n )

{v[k] = v[k+1];

k = k+1; }

Answer : while:

bge $s0, $s2, end # while (k < n)

addi $t0, $s0, 1 # $t0 = k+1

sll $t0, $t0, 2 # making k+1 indexable

add $t0, $t0, $s1 # $t0 = &v[k+1]

lw $t0, 0($t0) # $t0 = v[k+1]

sll $t1, $s0, 2 # making k indexable

add $t1, $t1, $s1 # $t1 = &v[k]

sw $t0, 0($t1) # v[k] = v[k+1]

addi $s0, $s0, 1

j while

end:

Explanation:

The MIPS assembly code corresponding to the C segment is

while:

bge $s0, $s2, end # while (k < n)

addi $t0, $s0, 1 # $t0 = k+1

sll $t0, $t0, 2 # making k+1 indexable

add $t0, $t0, $s1 # $t0 = &v[k+1]

lw $t0, 0($t0) # $t0 = v[k+1]

sll $t1, $s0, 2 # making k indexable

add $t1, $t1, $s1 # $t1 = &v[k]

sw $t0, 0($t1) # v[k] = v[k+1]

addi $s0, $s0, 1

j while
