left[0]=a[0];

for(int i=1;i<=n-1;i++)

left[i]=(left[i-1]*a[i])%M;

right[n-1]=a[n-1];

for(int i=n-2;i>=0;i--)

right[i]=(right[i-1]*a[i])%M;

Michael a programmer, is writing an algorithm to solve programming problems, Guide him to write an algorithm

Nadusha1986 [10]

Answer:

Algorithms need to be simple, factual, and explained in simple but relevant vocabulary, and must be step by step, and none of the step should be missing.

Hence, first you need to understand the requirement, which can be yours or your clients.

Then consider each module of the problem, and separate each of them from the others. Now, understand the relationship between each module. And then you need to understand how you can combine them in one algorithm.

Also remember, the modules are functions. and various functions combine together to form an algorithm. We can have separate algorithms for each module as well, and then you can combine them together in right continuity to form the one single program.

Also, a project can have a loads of programs with other parts like images and various other assets and technologies.

However, everything starts with algorithms. And if are good at explaining, and a sound vocabulary, plus can explain the process well, you can explain the process well, and write a good algorithm definitely. Learn languages like Python, C, and C++ to start with, and then continue with Java, R etc. Remember we still uses functional programming as well like through Haskell etc.

The below is an example of sample algorithm. John wants to check what Ana has brought for him.

Step 1: Ana arrives with meat, which can be of goat or chicken

Step 2: John: Hi Ana

Step3: Yes John

Step 4 What meat is that Ana

Step 5: Goat

Step 7: Thanks Ana for Bringng Goat Meat

Step 8: Stop

In the above algorithm John confirms that what meat Ana has brought for him. And he comes to know She has bought Goat meat. This is the simplest of algorithm with no loop. And the complexity can be increased to any level.

Explanation:

The Answer is self explanatory, and has all that is required.

Attackers have recently launched several attacks against servers in your organization’s DMZ. You are tasked with identifying a s

kari74 [83]

Answer:

Option B is correct.

Explanation:

Well into the DMZ corporation of the user, intruders have currently conducted numerous attempts toward networks. He is associated with finding any response which would provide the greatest opportunity in the future to avoid such threats.

The in-band IPS becomes the better approach for the required choices. Traffic moves via the IPS, as well as it has a better probability of avoiding inner processes through entering invasion.

Write the definition of a function divide that takes four arguments and returns no value . The first two arguments are of type i

Nastasia [14]

Answer:

#include <iostream>

using namespace std;

void divide(int numerator, int denominator, int *quotient, int *remainder)

{

*quotient = (int)(numerator / denominator);

*remainder = numerator % denominator;

}

int main()

{

int num = 42, den = 5, quotient=0, remainder=0;

divide(num, den, &quotient, &remainder);

return 0;

}

Explanation:

The exercise is for "Call by pointers". This technique is particularly useful when a variable needs to be changed by a function. In our case, the quotient and the remainder. The '&' is passing by address. Since the function is calling a pointer. We need to pass an address. This way, the function will alter the value at the address.

To sum up, in case we hadn't used pointers here, the quotient and remainder that we set to '0' would have remained zero because the function would've made copies of them, altered the copies and then DELETED the copies. When we pass by pointer, the computer goes inside the memory and changes it at the address. No new copies are made. And the value of the variable is updated.

Thanks! :)
