Question
backwards. However, there are no diagonal words.
Write an algorithm to find if the given word occurs in the grid on a row or a column, forward or backwards.
Input
The first line of input consists of two integers- grid_row and grid_col, representing the number of rows (N) and the number of columns (M) of the letter grid, respectively.
The next M lines consist of N space-separated characters representing the letters of the grid.
The next line consists of an integer-word_size, representing the number of words to be searched from the given grid (K).
The last line consists of K space-separated strings representing the words to search for in the grid.
Output
Print K space-separated strings consisting of "Yes" if the word is present in the grid or "No" if the word is not present in the grid.
Note
All the inputs are case-sensitive, meaning "a" and "A" are considered as two different characters.
Example
Input:
3 3
C A T
I D O
N O M
4
CAT TOM ADO MOM
Question
The next M lines consist of N space-separated characters representing the letters of the grid.
The next line consists of an integer-word_size, representing the number of words to be searched from the given grid (K).
The last line consists of K space-separated strings representing the words to search for in the grid.
Output
Print K space-separated strings consisting of "Yes" if the word is present in the grid or "No" if the word is not present in the grid.
Note
All the inputs are case-sensitive, meaning "a" and "A" are considered as two different characters.
Example

3 3
C A T
I D O
N O M
4
CAT TOM ADO MOM
Output:
Yes Yes Yes No
Explanation:
From the given words "CAT" is found at the first row, "TOM" is found at last column, "ADO" is found at the middle column, but "MOM" is not found anywhere in the grid.
So, the output is "Yes", "Yes", "Yes", "No".
Question
Starting from cell (1,1), her challenge is to hop in an anti-clockwise direction and skip alternate cells. The goal is to find out the last cell she would hop onto.
Write an algorithm to find the last cell Lucy would hop onto after moving anti-clockwise and skipping alternate cells.
Input
The first line of input consists of two integers- matrix_row and matrix_col, representing the number of rows (N) and the number of columns (M) in the matrix, respectively.
The next M lines consist of N space-separated integers representing the elements in each cell of the matrix.
Output
Print an integer representing the last cell Lucy would hop onto after following the given instructions.
Example
Input:
3 3
29 8 37
15 41 3
1 10 14
Output:
41
Explanation:
Lucy starts with 29, skips 15, hops onto 1, skips 10, hops onto 14, skips 3, hops onto 37, skips 8 and finally hops onto 41.
So, the output is 41.
Question
There is a set of N jars containing chocolates. Some of them may be empty. Determine the maximum number of chocolates Andrew can pick from the jars given that he cannot pick from jars next to each other.
Write an algorithm to find the maximum number of chocolates that can be picked from the jars in such a way that the chocolates are not picked from jars next to each other.
Input
The first line of input consists of an integer- numJars, representing the number of jars (N).
The next line consists of N space-separated integers representing the number of chocolates in each jar.
Output
Print the maximum number of chocolates that can be picked from the jars in such a way that the chocolates are not picked from jars next to each other.
Constraints
1 < N <= 1000
Example
Input:
6
5 30 99 60 5 10
Output:
114
