Andrew likes the topic of strings a lot and tries to solve as many problems as he could on this topic. He came

across a problem in which he was given two numbers in the form of strings and he was asked to subtract the second

number from the first and print the answer. The strings will contain numbers only.

Sample Run:

Input:

222

122

Output:

100

Andrew practices programming a lot and recently he came across the topic of pointers. He wondered if he could

use pointers to print all prime numbers from an array? Could you help him by writing a program which takes input

in an array and uses a pointer to find and print all the prime numbers from the array.

Sample Run:

Input:

1 2 3 4 5

Output:

2 3 5

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: 2072
