Check whether Two Strings are Anagrams of each other

Write a program to check whether two strings are anagrams of each other.

What is an Anagram ?

Two strings are said to be anagrams of each other if it contains the same characters, only the order of characters in both the strings is different. In other words, both strings must contain the same exact letters in the same exact frequency.

Generate Prime Numbers between 1 to N – Sieve of Eratosthenes

Write an efficient program to generate prime numbers between 1 to N (Where N is 10, 100, 1000 etc). This question can also be asked like this, Generate prime numbers between 1 to 100 or 1 to 10 etc.

Suppose the value of N is 10, So the prime numbers between 1 to 10 is 2, 3, 5, 7.  Now let’s learn the most efficient algorithm (Sieve of Eratosthenes) to generate Prime Numbers between 1 to N. Before solving this program, let’s understand what is a prime number.
