Concat

Concatenates two slices.

• Implement an appropriate function for each type.
• Use append() and the fact that it's a variadic function to concatenate the slices.

func ConcatInt(a,b []int) []int {
    return append(a, b...)
}
func ConcatFloat64(a,b []float64) []float64 {
    return append(a, b...)
}
func ConcatBool(a,b []bool) []bool {
    return append(a, b...)
}
func ConcatStrings(a,b []string) []string {
    return append(a, b...)
}

ConcatStrings([]string{"a", "b", "c"}, []string{"d", "e"}) // [a b c d e]
