let s = "This is C programming text";
let t = "This is a text for C programming";
//时间复杂度:O(n^2)
//空间复杂度:O(1)
function f1(str1,str2,r){
let arr1 = str1.split(" "),

if(r>Math.min(arr1.length,arr2.length)||r<1)return null;
//思路:1找出公共数组
for(let i=0;i {
if(!res[item.length]){
res[item.length] = item
}
});
//3剩下的排序
res.sort((a,b)=>a.length
//穷举法
//时间复杂度:O(n^2)
//空间复杂度:O(1)
function fn(num){
let res = [];
//找到符合条件的首个数字i和项数n
for(let i = 1;inum){

//输出
if(res.length>0){
let output = "";
res.forEach(item=>{

output+="\n";

红色:去过
绿色:计划去
功能点1:右键map添加计划
功能点2:右键未完成计划可更改完成状态和删除计划
功能点3:已去过的省份不可再次添加计划
功能点4:鼠标hover显示时间和备注
思路:
1.mockdata:
var dataSource = [
{
province:"黑龙江省",
point:{lng: 129.466081, lat: 44.625683},
desc:"my hometown",
time:"2018-7-5",
type:0,//0:去过,1:计划去
},{
province:"辽宁省",
point:{lng: 124.535605, lat: 41.979285},
desc:"2015年4月",
time:"2018-7-5",
type:0,//0:去过,1:计划去
},{
province:"北京市",
point:{lng: 116.146438, lat: 39.77318},
desc:"Dream start!",
time:"2018-7-5",
type:0,//0:去过,1:计划去
},{
province:"四川省",
point:{lng: 107.131762, lat: 30.083521},
desc:"计划今年十一去嗨!!",
time:"2018-7-5",
type:1,//0:去过,1:计划去
}
];
2.编写renderMark方法,实现data驱动ui变化
//渲染函数
function renderMark(){
map.clearOverlays();
dataSource.forEach((d,i)=>{
//渲染mark
var marker = new BMap.Marker(d.point,{
icon: new BMap.Symbol(BMap_Symbol_SHAPE_STAR, {
scale: 2,
fillColor: d.type===0 ? "red" : "#51C332",
fillOpacity: 0.8,
strokeColor:"#fff",
})
});
map.addOverlay(marker);
marker.setAnimation(d.type===0 ? BMAP_ANIMATION_DROP : BMAP_ANIMATION_BOUNCE); //动画
//渲染title
var title = "时 间: " + d.time + "\n\r" + "描 述: " + d.desc;
marker.setTitle(d.type===0 ? "已占领"+ "\n\r" +title:"计划"+ "\n\r" +title);
//为type=1的mark绑定右键编辑事件
if(d.type===1){
var menu = new BMap.ContextMenu();
var txtMenuItem = [
{
text:'标记完成',
callback:function(i){
dataSource[i].type=0;
renderMark()
}
},{
text:'删除计划',
callback:function(i){
dataSource.splice(i,1);
renderMark()
}
}
];
txtMenuItem.forEach(d2=>{
menu.addItem(new BMap.MenuItem(d2.text,d2.callback.bind(this,i),100));
})
marker.addContextMenu(menu);
}
})
}
