Answer:
def get_middle_ten(sentence):
ind = (len(sentence) - 12) // 2
return sentence[ind:ind + 12]
# Testing the function here. ignore/remove the code below if not required
print(get_middle_twelve("abcdefghijkl"))
print(get_middle_twelve("abcdefghijklmnopqr"))
print(get_middle_twelve("abcdefghijklmnopqrst"))
When it comes to front end, back end and full stack developer, the difference is determined by :
front end (the visible parts of a website)
back end (the “under the hood” databases and infrastructure)
full stack (a hybrid of both)
And front end developers work on technologies that are used to build front end(which is what clients visiting that website see)of application like HTML,CSS, Javascript ( Node js, Angular are also now used ).
Similarly back end developers work on back end technologies like Node js.
Full stack developers work on both front end and back end developers and know both end technologies as well.
For example :
MEAN Stack developer where
M stands for Mongoose ( Back end database technology )
E stands for Express ( Back end technology)
A stands for angular ( front end technology)
N stands for Node ( back end technology)
Answer:
Recursion is a process of defining a method that calls itself repeatedly
Explanation:
Recursion is a basic programming technique of defining a method that calls itself repeatedly.
One practical example is using recursion to find the factorial of a number.
Consider the following java code below, it uses recursion to solve for the factorial of a number.
class Main {
public static void main (String[] args) {
System.out.println("Factorial of 3 is " + factorial(3));
System.out.println("Factorial of 5 is " + factorial(5));
System.out.println("Factorial of 7 is " + factorial(7));
}
//the factorial method uses recursion to find the factorial of the
// parameter of the integer pass into it
private static int factorial(int n) {
int result;
if ( n ==1) return 1;
result = factorial(n-1) * n;
return result;
}
}
Answer:
An FPGA is a field programmable gate array. It could be "programmed" to do certain task, but don't mistake it with a microprocessor. When programming an FPGA, you're actually changing it's physical structure, the logic gates inside the FPGA, to do the task for you. Therefore, unlike a microprocessor which has to run through a series of command, an FPGA could be rewired to run at a much faster and more efficient rate.
FPGA is good for testbenching and are budget friendly since they can be reprogrammed over and over again in case you messed up. However, they can be quite big and bulky, so they are not suitable for mass production.
ASIC in the other hand can be compact to a small size. ASIC are pretty much the IC chips that you use, like your Intel CPU or LM7000 series chips. However, the process of making them that small is irreversible, so if you messed up, you gotta throw away the whole batch. This make them expensive to make, but their small size and production process allows them to be made in bulk.
Both FPGA and ASIC are good for power consumption and speed because you're actually designing their physical circuit layout, so if your design is efficient then the product will be efficient in both speed and power as well.
In Summary, you design and test your circuit using an FPGA first. Then you send that design to a production company and they will use that design to mass produce it as a small chip.
