The challenge
Given a string of words, return the length of the shortest word(s).
The input string will never be empty and you do not need to account for different data types.
The solution in Golang
Option 1:
package solution
import "strings"
func FindShort(s string) int {
shortest := len(s)
for _, word := range strings.Split(s, " ") {
if len(word) < shortest {
shortest = len(word)
}
}
return shortest
}
Option 2:
package solution
import "strings"
func FindShort(s string) (c int) {
words := strings.Split(s," ");
for _,word := range words {
if c == 0 || len(word) < c {
c = len(word);
}
}
return
}
Option 3:
package solution
import "strings"
func FindShort(s string) (c int) {
for _, word := range strings.Fields(s) {
if c == 0 || len(word) < c {
c = len(word)
}
}
return c
}
Test cases to validate our solution
package our_test
import (
. "github.com/onsi/ginkgo"
. "github.com/onsi/gomega"
)
var _ = Describe("Test Example", func() {
It("should test that the solution returns the correct value", func() {
Expect(FindShort("bitcoin take over the world maybe who knows perhaps")).To(Equal(3))
Expect(FindShort("turns out random test cases are easier than writing out basic ones")).To(Equal(3))
Expect(FindShort("Let's travel abroad shall we")).To(Equal(2))
})
})
