javascript 每个第n个数组总和

Posted 2021-05-03

function nthArrSum(n, targetSum, arr) {
  var count = 0;
  var sum = 0;
  for(var i=0; i<arr.length; i++) {
    count++;
    if(count === n) {
      count =0;
      sum = getSum(arr[i]);
      if(sum <= targetSum) {
        console.log("not correct");
        return;
      }
    }
  }
  
  console.log("yess");
}

function getSum(arr) {
  var total = 0;
  for(var j=0; j<arr.length; j++) {
    total += arr[j];
  }
  return total;
}

nthArrSum(3, 10, [[0,-1,-2], [2], [3,6,6], [4], [-1,-3], [5,5,8], [7], [9], [2,4,5], [0]]);
