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

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))
  })
})
