Answer:
def sum_1k(M):
s = 0
for k in range(1, M+1):
s = s + 1.0/k
return s
def test_sum_1k():
expected_value = 1.0+1.0/2+1.0/3
computed_value = sum_1k(3)
if expected_value == computed_value:
print("Test is successful")
else:
print("Test is NOT successful")
test_sum_1k()
Explanation:
It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.
- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.
- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message
- Call the <em>test_sum_1k()</em> to see the result
Answer:
Explanation:
Before answering this question we need to first know the differences between System Mode and User Mode.
System Mode mainly runs code and at the same time overlooking the user's privileges and permissions.
the attribute(s) that belongs to the user model includes:
User Mode
- User programs typically execute in this mode
- Less-privilege mode
while the attribute(s) that belongs to the system model includes:
System Mode
- Also referred to as control mode or kernel mode
- Kernel of the operating system
- More-privilege mode
Answer:
public class Calculator {
public double add(int a, int b){
return a+b;
}
public double substract(int a, int b){
return a-b;
}
public double multiply(int a, int b){
return a*b;
}
public double divide(int a, int b){
if(b>0){
return a/b;
}
else{
System.out.println("Cannot divide by zero");
}
return -1;
}
}
Explanation:
- Using Java Programming Language, the class Calculator is created. There are no fields (Instance variables) and no constructors since these are not required by the question.
- Four methods (functions) are created: add, substract, multiply and divide as specified in the question.
- Note the use of the if statement in the divide() to handle case of illegal division (by 0)
