Golang : Find the shortest line of text example
Continue from previous tutorial on how to find the longest line in a given text. This example demonstrates how to find the shortest line in a given text file. Can be useful in a situation where you want to find shortest lines to discard from a raw data file.
Here you go!
package main
import (
"fmt"
"strings"
)
func shortestLine(input string) (shortest string) {
lines := strings.Split(input, "\n")
size := len(lines[0]) // init with first line length
for _, v := range lines {
//fmt.Println(k,v, "Size: ", len(v))
if len(v) <= size {
shortest = v
size = len(v)
}
}
return
}
func main() {
text := `line 1
line 2 line 3 line 4
line 5 line 6 line 7 line 8 line 9 line 10
line 11 line 12
line 13 line 14 line 15
shortest
no!`
//fmt.Println(text)
// find the shortest line in text and display it
fmt.Println("Shortest: ", shortestLine(text))
}
Shortest: no!
