Photography allows us to view the world around us in different ways, by giving us the sense and feel of what others feel, Photography is art. You are able to use photography to define actions, for example happiness in a marriage or happiness in children playing at the park. Photography also allows you to explore and discover new things, and make something out of that. It makes you think a bout different ways to change the world around you, how do you define the world?

In an array, we can swap the elements at any two indices in a single operation called a move. For example, if our array is a = {

quester [9]

Answer:

function moves(a) {

var left = 0;

var right = a.length-1;

var count = 0;

while (left < right) {

if(a[left] % 2 == 0) {

left++;

continue;

}

if(a[right] % 2 == 1) {

right--;

continue;

}

var temp = a[left];

a[left] = a[right];

a[right] = temp;

left++;

right--;

count++;

}

return count;

}

var a = [4,13,10,21,20];

console.log('Number of moves: ' + moves(a));

console.log('Sorted array: ' + a);

Write a program to solve the selection problem. Let k = N/2. Draw a table showing the running time of your program for various v

Brums [2.3K]

So here is the code in Python:

n = 0.00 #this is a float because there are some numbers that are decimals.

while n < 20: #n which is 0.00 and while it is lower than 20 if runs the code below
n = n + 1 #it will add 1 to n everything it runs the code.
k = n / 2 #it will divide whatever n is everytime by 2
print(str(n) + '/2: ') # it's printing the number it's on
print(k) # prints the answer for the n.

You can change n to add by any, make n any num instead of 0.00 and you can change the while condition from n < 20 to any other logical statement. If you want to get creative you can take 2 inputs for numbers and make one of them the starting number and other one is the ending number. Also make sure to make n a number lower than you starting point because if you set n as your starting point then it will skip it.

A = [2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 33 34 35 36 37 38 39 40]

vova2212 [387]

Answer:

$C = a./b$

Explanation:

In MATLAB, the following command:

$C = A./B$

Performs the element by elemet division of A and B. This comand is called Right-array division.

So, in your case, we could divide A by B element by element, only using fully-vectorised code (ie. no loops), with the following code:

$a = [2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 33 34 35 36 37 38 39 40];b = [1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 43 45 47 49 50 54 59 60];C = a./b$ ;

C would be the element by element division of A and B, with no loops.

If an LED had power rating of 150 milliwatts at 1.5 volts , how much current is used

Lana71 [14]

The relation between Power, Current and Voltage is given as:

P = V i

where P is Power in Watts,

V is Voltage in Volts,

and i is Current in Ampere.

We are given:

Power = 150 milliwatts = 0.15 Watts

(as 1 milliwatt = 0.001 Watts)

Voltage = 1.5 volts

and we need to find the current.

Hence using above equation:

P = V i

i = $\frac{P}{V}$

i = $\frac{0.15}{1.5}$

i= 0.1 Ampere

Answer:

The current used is 0.1 Ampere
