You are given a positive integer ‘n’. Your task is to find the largest prime factor of this given positive integer.

Note :

If there is no prime factor of a given integer, then print -1.

Ninja is feeling very bored and wants to try something new. So, he decides to find the reverse of a given number. But he cannot do it on his own and needs your help.

Note:

If a number has trailing zeros, then its reverse will not include them. For e.g., the reverse of 10400 will be 401 instead of 00401.

You are given an integer ‘N’. Your task is to find out the ‘N’th Tribonacci Number. ‘N’th number in the Tribonacci sequence is defined as T_n = T _{n - 1} + T_{n - 2} + T_{n - 3}. Where T₀ = 0, T₁ = 1, T₂= 1. Return the answer in mod of 10⁹ + 7.

For Example :

You are given ‘N’ = 5, Here we know 0th, 1st and 2nd Tribonacci numbers are 0, 1 and 1 respectively. Therefore we can calculate the 3rd number as 0 + 1 + 1 = 2 and 4th number as 1 + 1 + 2 = 4 and 5th number as 1 + 2 + 4 = 7. Hence the answer is 7.

You are given a Singly Linked List of integers. Return true if it has a cycle, else return false.

A cycle occurs when a node's next points back to a previous node in the list.

Example:

In the given linked list, there is a cycle, hence we return true.

Print the following pattern
