func minCut(s string) int {n := len(s)g := make([][]bool, n)for i := range g {g[i] = make([]bool, n)for j := range g[i] {g[i][j] = true}}for i := n - 1; i >= 0; i-- {for j := i + 1; j < n; j++ {g[i][j] = s[i] == s[j] && g[i+1][j-1]}}f := make([]int, n)for i := range f {if g[0][i] {continue}f[i] = math.MaxInt64for j := 0; j < i; j++ {if g[j+1][i] && f[j]+1 < f[i] {f[i] = f[j] + 1}}}return f[n-1]
}
