问题分析

题设给定多组数值, 要求分别输出每组数中的最大值, 以及输出全部数值的最大值。so easy.

完整描述步骤

1. 获取输入: 小组数量, 小组规模
2. 初始化计数器:
   • 小组最重
   • 全体最重 = 0
3. 对于每一个小组:
   • 重置 小组最重 值为 = -1
   • 获取输入: 各个小组成员的体重
   • 对于每一个体重:
     • 如果当前体重大于当前小组最重:
       • 更新小组最重 = 当前体重
   • 输出小组最重
   • 如果当前小组最重大于当前全体最重:
     • 更新全体最重 = 当前小组最重
4. 输出全体最重

伪代码描述

1. get input: group_amont, group_size
2. init recorder:
   • weight_group_champion
   • weight_final_champion = -1
3. for each group:
   • weight_group_champion = -1;
   • get input: weights
   • for each weight:
     • if weight > weight_group_champion:
       • weight_group_champion = weight
   • print(weight_group_champion)
   • if weight_group_champion > weight_final_champion:
     • weight_final_champion = weight_group_champion;
4. print(weight_final_champion)
