What is output by the following code?

1 answer:

8 0

When numbers are divided, the integer portion is kept and the remainder is disregarded (meaning 10/9 would return 1). Following this format, we get the answer of 6 6 6 3 7 7 9 5 8 8.
I also see that this program can be optimized because you use the same for loop twice, and both of them manipulate list elements in some way. A more optimized program would be:

int a [] = {64 , 66 , 67 , 37 , 73 , 70 , 95 , 52 , 81 , 82};

for (int i = 0; i < a.length; i++) {
a[i] = a[i] / 10;
System.out.print(a[i] + " ");
}

Or maybe you don't need to store the list values for later on. You could do:

for (int i = 0; i < a.length; i++) {
System.out.print(a[i] / 10 + " ");
}

In any situation, your answer is choice 2.

In which type of market do farmers sell their produce directly to village traders in rural areas?

Anna007 [38]

Answer:

Local Market or Primary Market.

Explanation:

The farmers sell their products to big traders in the bigger market in the urban areas. However, they also sell a part of their products to various village traders, who are located in the rural areas and can be found in local or primary markets. It's not so that they are not useful as well, as small farmers, in fact, sell the whole of their produce in the local or primary market as we know them by name. And the farmer gets a reasonable return there as well.

Write a function called st_dev. St_dev should have one #parameter, a filename. The file will contain one integer on #each line.

kodGreya [7K]

Answer:

import statistics
def st_dev(file_name):
with open(file_name) as file:
data = file.readlines()
numList = []
for x in data:
numList.append(int(x))
return statistics.pstdev(numList)
print(st_dev("text1.txt"))

Explanation:

The solution code is written using Python.

To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).

Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.

We test the function by passing a file which hold a list of integer values in each line (Line 12).

And the output we shall get is 4.019950248448356
