CPTTRN5 - Character Patterns (Act 5)

Using two characters: . (dot) and * (asterisk) print a grid-like pattern. The grid will have l lines, c columns, and each square shaped element of the grid will have the height and width equal to s.

Moreover, each of the grid elements will have a diagonal. The diagonal of the first square in the first line of the grid is directed towards down and right corner - use the \ (backslash) character to print it; while the next diagonal will be directed towards upper right corner - use the / (slash) character to print it. Print the successive diagonals alternately (please consult the example below).


You are given t - the number of test cases and for each of the test case three positive integers: l - the number of lines, c - the number of columns in the grid and s - the size of the single square shaped element.


For each of the test cases output the requested pattern (please have a look at the example). Use one line break in between successive patterns.

I'm doing CPTTRN7 and CPTTRN8 before doing this one!

Divide it into the 4 sections (even and odd by row, and even and odd by column) That really helped me

Can s be greater than l ??

Why "wrong answer" when my program give the same answer as example???

My solution runs well on ideone but I am getting wrong answer here on spoj. Please can you give me the solution?

hint - for slashes think of property of diagonals of a square.

I thought it will be hard for me to solve it but, when I read the question I did it in not more than 10 mins.
