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