I started my journey by getting admission in NSUT. After exploring different coding languages and by taking guidance from seniors I started coding in c++ as it can help me in competitive level also.

In 4th year I have made a project based on Machine learning and Web development.

You are given a positive integer ‘N’. Your task is to print all prime numbers less than or equal to N.

Note: A prime number is a natural number that is divisible only by 1 and itself. Example - 2, 3, 17, etc.

You can assume that the value of N will always be greater than 1. So, the answer will always exist.

You are given two strings 'str1' and 'str1'.


You have to tell whether these strings form an anagram pair or not.


The strings form an anagram pair if the letters of one string can be rearranged to form another string.

Pre-requisites:

Anagrams are defined as words or names that can be formed by rearranging the letters of another word. Such as "spar" can be formed by rearranging letters of "rasp". Hence, "spar" and "rasp" are anagrams. 

Other examples include:

'triangle' and 'integral'
'listen' and 'silent'
Note:
Since it is a binary problem, there is no partial marking. Marks will only be awarded if you get all the test cases correct.
