题解:
func isSubseq(s, t string) bool {
ptS := 0
for ptT := range t {
if s[ptS] == t[ptT] {
if ptS++; ptS == len(s) {
return true
}
}
}
return false
}
func findLUSlength(strs []string) int {
ans := -1
next:
for i, s := range strs {
for j, t := range strs {
if i != j && isSubseq(s, t) {
continue next
}
}
if len(s) > ans {
ans = len(s)
}
}
return ans
}
