SDE - 1

Ninja has been given a number that is represented in the form of a linked list such that each digit corresponds to a node. He has been asked to add 1 to it and return the updated list.

For Example:

1234 is represented as (1 -> 2 -> 3 -> 4) and adding 1 to it should change it to (1 -> 2 -> 3 -> 5).

Note:

The input Linked list does not have any trailing zeros.

You are given two strings S and X containing random characters. Your task is to find the smallest substring in S which contains all the characters present in X.

Example:

Let S = “abdd” and X = “bd”.

The windows in S which contain all the characters in X are: 'abdd', 'abd', 'bdd', 'bd'. 
Out of these, the smallest substring in S which contains all the characters present in X is 'bd'. 
All the other substring have a length larger than 'bd'.

Write a query to display the records which have 3 or 
more consecutive rows and the amount of people more than 100(inclusive).

-- X city built a new stadium, each day many people visit it and 
the stats are saved as these columns: id, visit_date, people

-- Please write a query to display the records which have 3 or 
more consecutive rows and the amount of people more than 100(inclusive).

-- For example, the table stadium:
-- +------+------------+-----------+
-- | id | visit_date | people |
-- +------+------------+-----------+
-- | 1 | 2017-01-01 | 10 |
-- | 2 | 2017-01-02 | 109 |
-- | 3 | 2017-01-03 | 150 |
-- | 4 | 2017-01-04 | 99 |
-- | 5 | 2017-01-05 | 145 |
-- | 6 | 2017-01-06 | 1455 |
-- | 7 | 2017-01-07 | 199 |
-- | 8 | 2017-01-08 | 188 |
-- +------+------------+-----------+
-- For the sample data above, the output is:

-- +------+------------+-----------+
-- | id | visit_date | people |
-- +------+------------+-----------+
-- | 5 | 2017-01-05 | 145 |
-- | 6 | 2017-01-06 | 1455 |
-- | 7 | 2017-01-07 | 199 |
-- | 8 | 2017-01-08 | 188 |
-- +------+------------+-----------+
