Description

Generate an arrayList with given size, initialize the array list with numbers from 1 to size.

Example

Given size = 4. return an array list that contains numbers from 1 to 4: 1,2,3,4]

i<size+1 比 i<=size 更快

public class Solution {
    /**
     * @param size: An integer
     * @return: An integer list
     */
    public List<Integer> generate(int size) {
        // write your code here
        
        List<Integer> list = new ArrayList<>();
        for (int i=1; i<size+1; i++){
            list.add(i);
        } 
        return list;
        
    }
}
描述
给你一个大小size,生成一个1-size的数组
