题解:
func checkSubarraySum(nums []int, k int) bool {m := len(nums)if m < 2 {return false}mp := map[int]int{0: -1}remainder := 0for i, num := range nums {remainder = (remainder + num) % kif prevIndex, has := mp[remainder]; has {if i-prevIndex >= 2 {return true}} else {mp[remainder] = i}}return false
}
