A sample program to rotate all the elements in a n x n array that form square edges. For instance: [1,2,3,4] will be treated as a matrix of 2x2 and will be rotated to output [3,1,4,2]. This matrix had possibly no sub-square, but the likes of 5x5 that do hold a sub-square matrix of 3x3 will be rotated and transformed accrodingly.
- Node
- Npm/ Yarn
- CSV file with data (example below)
- Install the package dependencies by running
npm ioryarn install - Build using
npm run buildoryarn build - Execute -
node .\cli.js input.csv > output.csv
On successful execution you could see the output.csv file with result.
- The program expects input in the form of a csv file. The content should be in the following format:
id,json
0,"[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]"
56,"[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]"
1,"[1,2,3,4,5,6,7,8,9]"
2,"[40,20,90,10]"
3,[-5]
9,"[2, -0]"
5,"[2,-5,-5]"
8,"[1,1,1,1,1]"
You can expect the output to be like:
id,json,is_valid
0,[5,1,2,3,9,10,6,4,13,11,7,8,14,15,16,12],true
56,[6,1,2,3,4,11,12,7,8,5,16,17,13,9,10,21,18,19,14,15,22,23,24,25,20],true
1,[4,1,2,7,5,3,8,9,6],true
2,[90,40,10,20],true
3,[-5],true
9,[],false
5,[],false
8,[],false
- The build command might possibly fail due to presence of old build files. In that case simply delete the
cli.jsandutil.jsfiles in the root and re-run the build command.
