今天学的是循环嵌套，没什么笔记，就写几个例题吧 1，输出直角三角形 题目描述 给出一个整数 𝑛 和一个字符 𝑐，输出一个由字符 c 围成的实心三角形，具体参照样例（1<𝑛≤100)。 输入格式 每组样例第一行一个整数 𝑛 和一个字符 𝑐，用空格隔开。 输出格式 每组样例输出 𝑛 和字符 𝑐 所对应的实心三角形。 2，输出倒反直角三角形 题目描述 给出一个整数 𝑛和一个字符 𝑐，输出一个由字符 𝑐 围成的倒反实心三角形，具体参照样例（1<𝑛≤100)。 输入格式 每组样例第一行一个整数 𝑛和一个字符 𝑐，用空格隔开。 输出格式 每组样例输出 𝑛和字符 𝑐 所对应的倒反实心三角形。 3，输出实心菱形 题目描述 给出一个整数 𝑛 和一个字符 𝑐，输出一个由字符 𝑐 围成的实心菱形，具体参照样例（1<𝑛≤100)。 输入格式 每组样例第一行一个整数 𝑛 和一个字符 𝑐，用空格隔开。 输入输出样例 输入#1 输出#1
