+我们从左到右遍历字符串 $\textit{target}$，用变量 $\textit{ans}$ 记录翻转次数。 当遍历到下标 $i$ 时，如果当前的翻转次数 $\textit{ans}$ 的奇偶性与 $\textit{target}[i]$ 不同，则需要在下标 $i$ 处进行一次翻转操作，将 $\textit{ans}$ 加 $1$。

-### Solution 1
+### Solution 1: Greedy
+
+We traverse the string $\textit{target}$ from left to right, using a variable $\textit{ans}$ to record the number of flips. When we reach index $i$, if the parity of the current flip count $\textit{ans}$ is different from $\textit{target}[i]$, we need to perform a flip operation at index $i$ and increment $\textit{ans}$ by $1$.

+The time complexity is $O(n)$, where $n$ is the length of the string. The space complexity is $O(1)$.
