+# loafofbread
+
+### Instructions
+
+Write a function `LoafOfBread()` that takes a string and returns another one with words of 5 characters and skips the next character followed by newline `\n`.
+
+- If there is a space in the middle of a word it should ignore it and get the first character until getting to a length of 5.
+- If the string less than 5 characters returns "Invalid Output\n"
+-
+### Expected function
+
+```go
+func LoafOfBread(str string) string {
+}
+```
+
+### Usage
+
+Here is a possible program to test your function :
+
+```go
+package main
+
+import "fmt"
+
+func main() {
+	LoafOfBread("deliciousbread")
+  LoafOfBread("This is a loaf of bread")
+  LoafOfBread("Bread crumbles")
+  fmt.Print(LoafOfBread("deliciousbread"))
+  fmt.Print(LoafOfBread("This is a loaf of bread"))
+  fmt.Print(LoafOfBread("loaf"))
+}
+```
+
+And its output :
+
+```go
+$ go run . | cat -e
+delic ousbr ad$
+Thisi ashor sente ce$
+This  s a l af of bread$
+Invalid Output$
+```
