大佬们遇到过这个问题吗？如何让数组两两分组，然后相加求老司机指点！

Question

我有一个数组[0,0,40,0,60,85,125,0,0,40,110,0,70,110,0,0,0,30,0,0,30]现在两两分组相加，他把变成[0,40,145,125,40,110,180,0,30,0,30]多出来的30不相加，保留我现在lettenMinTotalAdd=[]for(vari=0;i

Answer 1

letarray=[1,2,3,23,4,5]
letres=[]
array.filter((item,index,arr)=>{
if((index+1)%2==1){
letsum=arr[index]+(arr[index+1]||0);
res.push(sum)
}
})
//res应该是你需要的结果
                            

Answer 2

lettenMinTotalArray=[0,0,40,0,60,85,125,0,0,40,110,0,70,110,0,0,0,30,0,0,30]
lettenMinTotalAdd=[]
for(vari=0;iletslice=tenMinTotalArray.slice(i,i+2)
tenMinTotalAdd.push(
slice.reduce(function(prev,curr,idx,arr){
returnprev+curr
})
)
}
你都整理出来了不考虑时间、空间复杂度，遍历就行
