Find latitude and longitude of first 20 countries with a population greater than or equal to the population limit given below. Use the country details from this dataset.

Your task is to find the sum of the length of all lines (in kms) that can be drawn between co-ordinates of these countries.

• Assume radius of earth: 6371 km
• Round length of each line and final result to 2 decimal points
• If co-ordinates are missing for any country use 0.000 N 0.000 E

Population limit: 300

Consider a square matrix , a size n*n and a integer , x . Calculate the row number , r and column , c or x in a. If the sum of R and C is an even number, find the sum s of all even numbers in the matrix and if the sum of r and c is odd , then find the sum s of all odd numbers in the matrix.

WITH COMMENTS AND EXPLANATION

Create a program with comments that can record the name, gender, and grades of a student in a certain subject. The grades consist of 1st, 2nd, 3rd, and 4th quarters.

The program should be able to do the following:

• Add new student

• Set student grades

• Show all students w/ grades

• Show student grade remarks (PASS or FAILED), passing mark is >= 75

• Search student record

The program should use the following features:

• Array

• Class

• Specific Sorting Algorithm (Bubble, Selection, Insertion, Merge, Shell)

• Specific Searching Algorithm (Linear, Binary, Fibonacci, Jump)

I'm quite into games now, so how about we play In or Out! When a given number is even, the team scores so we shall print "In", but if it's not an even number, then we print "Out". Simple, right?

Give example of chained conditional

1. Time measurement using song duration

Consider that Alice is cycling from point A to point B. During the cycling, Alice is listening to songs in her music player.

Given the following inputs:

1. The distance between A and B in metres

2. The speed at which Alice is traveling in metres per second

3. Duration of each song in her playlist in the

following format: mm:ss

the program should:

• Print the number of the song that Alice is listening when the cycling is completed from A to B

· Print Invalid input if any of the constraints mentioned in the constraints section is violated

Example 1

Consider the following inputs:

2000

5

Now consider the following list of songs:

05:30

02:04

Describe the difference between a chained conditional and a nested conditional. Give your own example of each. Do not copy examples from the textbook.

Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional.
