Locker doors There are n lockers in a hallway, numbered sequentially from 1 to n. Initially, all the locker doors are closed. Yo

kow [346]

Answer:

// here is code in C++

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

int n,no_open=0;

cout<<"enter the number of lockers:";

// read the number of lockers

cin>>n;

// initialize all lockers with 0, 0 for locked and 1 for open

int lock[n]={};

// toggle the locks

// in each pass toggle every ith lock

// if open close it and vice versa

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

{

for(int a=0;a<n;a++)

{

if((a+1)%i==0)

{

if(lock[a]==0)

lock[a]=1;

else if(lock[a]==1)

lock[a]=0;

}

cout<<"After last pass status of all locks:"<<endl;

// print the status of all locks

for(int x=0;x<n;x++)

{

if(lock[x]==0)

{

cout<<"lock "<<x+1<<" is close."<<endl;

}

else if(lock[x]==1)

{

cout<<"lock "<<x+1<<" is open."<<endl;

// count the open locks

no_open++;

}

// print the open locks

cout<<"total open locks are :"<<no_open<<endl;

return 0;

}

Explanation:

First read the number of lockers from user.Create an array of size n, and make all the locks closed.Then run a for loop to toggle locks.In pass i, toggle every ith lock.If lock is open then close it and vice versa.After the last pass print the status of each lock and print count of open locks.

Output:

enter the number of lockers:9

After last pass status of all locks:

lock 1 is open.

lock 2 is close.

lock 3 is close.

lock 4 is open.

lock 5 is close.

lock 6 is close.

lock 7 is close.

lock 8 is close.

lock 9 is open.

total open locks are :3

Create a goal seek analysis to determine what the price should be to generate demand of 2,625,000 tablets given that the supplie

Svetach [21]

Answer:

Explanation:

The following image shows the required entries that are to be filled in the excel sheet:

Goal Seek Parameters and Results

Set Cell C14

To Value By Changing Cell 2625000

By Changing Cell C3

Resulting Price? $290

Explanation:

The goal seek tool in excel is used to change a value in the calculation to get the desired results.

In the given question, it is required to get the demand of tablets to reach the value of 2,625,000 by changing the price.

The value that is to be inserted in the “Set cell” field is the cell number which shall contain the desired result. This cell must have a formula having the cell which is inserted in the “by changing cell” field.

In the given question, the value of demand is desired.

The cell value which stores the calculated demand is C14 is and hence it is inserted in the field “Set cell”

The “to value” field of the goal seek tool is used to set the desired result.

Here, 2,625,000 is the value that is desired and hence it filled in the “To value” field.

The “By changing cell” field of the goal seek tool, represents the cell whose value is to be changed for getting the desired results.

Here, the value of price is required to be changed to get the required demand, thus the value that should be inserted in the “By changing cell” of the goal seek tool is C3, which represents the price.

The required demand is achieved by changing the price to $290.

What is the smallest integer n (stored as a floating point value) such that n + 1.0 - n will produce 0.0 for: a) Single-precisio

Vedmedyk [2.9K]

Answer: The FP-s are stored as sign (1.)111111111111 - number of bits.

Also 24 bits resolution there can be 23 zeros

Explanation:

The –1·2²⁴ might be stored as -1 · 1.00000000000000000000000(1 ←the 2⁰), it depends on how the FFP “engine” manages this, it may also be code specific a n+1–n does return 1 but 1–n+n does not. you should carry out a test for a specific compiler/computer

This is what javascript does with double (k+=1; n-=1) e.g

the (k+=2; n-=2) should be used to pass ±0x20000000000000
