func findMaxLength(nums []int) (maxLength int) {
mp := map[int]int{0: -1}
counter := 0
for i, num := range nums {
if num == 1 {
counter++
} else {
counter--
}
if prevIndex, has := mp[counter]; has {
maxLength = max(maxLength, i-prevIndex)
} else {
mp[counter] = i
}
}
return
}
func max(a, b int) int {
if a > b {
return a
}
return b
}
