CPTTRN3 - Character Patterns (Act 3) |
Using two characters: . (dot) and * (asterisk) print a grid-like pattern.
Input
You are given t - the number of test cases and for each of the test cases two positive integers: l - the number of lines and c - the number of columns in the grid. Each square of the grid is of the same size and filled with 4 dots (see the example below).
Output
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.
Example
Input: 3 3 1 4 4 2 5 Output: **** *..* *..* **** *..* *..* **** *..* *..* **** ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* **************** *..*..*..*..*..* *..*..*..*..*..* **************** *..*..*..*..*..* *..*..*..*..*..* ****************

the logic for the number of lines and columns : <snip> [NG]: ... is for each to find on one's own. Last edit: 2021-05-13 12:45:11 |

My hint is to use strings that include "\n". AC for the first time. |

It's easy problem, I tried many times but at last i knew the trick, its a little math trick, take a deep lock into the pattern and you will guess it |

Use this simple logic to calculate the total number of lines and columns : l = (l + 1) + ( l * 2 ) c = (c + 1) + (c * 2) now apply the logic to add stars and dots stars will be applied at first line and the lines which give 0 on mod 3, same is the case with columns |
