Given two strings, 'S' and 'T' with lengths 'M' and 'N', find the length of the 'Longest Common Subsequence'.

For a string 'str'(per se) of length K, the subsequences are the strings containing characters in the same relative order as they are present in 'str,' but not necessarily contiguous. Subsequences contain all the strings of length varying from 0 to K.

Example :

Subsequences of string "abc" are:  ""(empty string), a, b, c, ab, bc, ac, abc.

In one box there are 12 red and 12 green balls and in another box there are 24 res and 24 green balls.
You have two balls choose from each of the box with replacement such that they have the same colour.
Which of the box has a better probability.

You are working as a cab driver. Your car moves in a straight line and moves toward the forward direction only. Initially, you have ‘C’ empty seats for the passengers.

Now, you are given ‘N’ number of trips that you have to make. In each trip, you are given three integers ‘Num’, ‘pickPoint’, and ‘dropPoint’ denoting that there are ‘Num’ numbers of passengers standing at 'pickpoint’ and you have to drop them at 'droppoint’.

Your task is to find if it is possible to pick up and drop off all the passengers of all the given trips or not.

Note :

You have a special type of car containing any number of seats.

The n-th term of Fibonacci series F(n), where F(n) is a function, is calculated using the following formula -

    F(n) = F(n - 1) + F(n - 2), 
    Where, F(1) = 1, F(2) = 1

Provided 'n' you have to find out the n-th Fibonacci Number. Handle edges cases like when 'n' = 1 or 'n' = 2 by using conditionals like if else and return what's expected.

Example :

Input: 6

Output: 8

Explanation: The number is ‘6’ so we have to find the “6th” Fibonacci number.
So by using the given formula of the Fibonacci series, we get the series:    
[ 1, 1, 2, 3, 5, 8, 13, 21]
So the “6th” element is “8” hence we get the output.
