下面是使用Go语言泛型实现的in_array函数。这个函数接受一个类型参数T,这样它就可以处理任何类型的数据。 packagemainimport("fmt")funcInArray[T any](val T,array[]T)bool{for_,item:=rangearray{ifitem==val{returntrue}}returnfalse}funcmain(){array:=[]int{1,2,3,4,5}fmt.Println(InArray(3,array...

通过array的切片可以切出slice,也可以使用make创建slice,此时golang会生成一个匿名的数组。 因为slice依赖其底层的array,修改slice本质是修改array,而array又是有大小限制,当超过slice的容量,即数组越界的时候,需要通过动态规划的方式创建一个新的数组块。把原有的数据复制到新数组,这个新的array则为slice新的底层依赖。
