力扣 1662. 检查两个字符串数组是否相等

解法

def arrayStringsAreEqual(word1, word2):
    j, c_j, cur2, w2_num = 0, 0, word2[0], len(word2)
    for i in range(len(word1)):
        for c in word1[i]:
            if c_j >= len(cur2):
                j += 1
                if j >= w2_num:
                    return False
                cur2 = word2[j]
                c_j = 0
            # print(c, cur2[c_j])
            if c != cur2[c_j]:
                return False
            c_j += 1
    if j + 1 < w2_num or c_j < len(cur2):
        return False
    return True
