概述1) Append a slice b to an existing slice a: a = append(a, b...) 2) Copy a slice a to a new slice b: b = make([]T, len(a)) copy(b, a) 3) Delete item at index i: a = append(a[:i], a[i+1:]...) 4) Cut fro 1) Append a slice b to an existing slice a: a = append(a,b...) 2) copy a slice a to a new slice b: b = make([]T,len(a)) copy(b,a) 3) Delete item at index i: a = append(a[:i],a[i+1:]...) 4) Cut from index i till j out of slice a: a = append(a[:i],a[j:]...) 5) Extend slice a with a new slice of length j: a = append(a,make([]T,j)...) 6) Insert item x at index i: a = append(a[:i],append([]T{x},a[i:]...)...) 7) Insert a new slice of length j at index i: a = append(a[:i],append(make([]T,j),a[i:]...)...) 8) Insert an existing slice b at index i: a = append(a[:i],append(b,a[i:]...)...) 9) Pop highest element from stack: x,a = a[len(a)-1],a[:len(a)-1] 10) Push an element x on a stack: a = append(a,x) 总结
