slice

Gists This is a sample script for sorting a slice using Golang. Recently, I had a situation for sorting the coordinates of cells of Spreadsheet. As a test case, it thinks of the situation that the randomized cells are sorted. I think that this can be also used for a table except for Spreadsheet. Sample slice: The sample slice is as follows. ar := []struct { row int col int value string }{ {0, 0, "A1"}, {0, 1, "B1"}, {0, 2, "C1"}, {1, 0, "A2"}, {1, 1, "B2"}, {1, 3, "D2"}, {2, 0, "A3"}, {2, 2, "C3"}, } When each element of above slice is put to a Spreadsheet, it becomes as follows.

Gists This is a sample script for transposing slice from (n x m) to (m x n) for golang. Script : package main import "fmt" func transpose(slice [][]string) [][]string { xl := len(slice[0]) yl := len(slice) result := make([][]string, xl) for i := range result { result[i] = make([]string, yl) } for i := 0; i < xl; i++ { for j := 0; j < yl; j++ { result[i][j] = slice[j][i] } } return result } func main() { sample := [][]string{ []string{"a1", "a2", "a3", "a4", "a5"}, []string{"b1", "b2", "b3", "b4", "b5"}, []string{"c1", "c2", "c3", "c4", "c5"}, } ar := transpose(sample) fmt.
