每日刷题【day008】

1、子数组最大平均数 I

public double findMaxAverage(int[] nums, int k) {
    int sum=0;
    for (int i=0;i<k;i++){
        sum+=nums[i];
    }
    int maxSum=sum;
    for (int i=k;i<nums.length;i++){
        sum=sum-nums[i-k]+nums[i];
        maxSum=Math.max(sum,maxSum);
    }
    return 1.0*maxSum/k;
}

2、移除元素

public int removeElement(int[] nums, int val) {
    int res=0;
    for (int i=0;i<nums.length;i++){
        if (nums[i]!=val) nums[res++]=nums[i];          
    }
    return res;
}
