一元稀疏多项式计算器,2． 用户在首先在第一个提示信息的提示下选择是1.一元多项式加法 2.一元多项式减法 3.退出，当用户选择1.一元多项式加法，系统会提示您输入两个多项式信息，然后计算两个多项式的和并输出结果多项式。当用户选择2.一元多项式减法，系统会提示您输入两个多项式信息，然后计算两个多项式的差并输出结果多项式。当用户选择退出，则退回dos-one yuan sparse polynomial calculator, 2. Users first in a message prompted by a choice. One yuan polynomial Adder 2. One yuan polynomial subtraction 3. From that when users choose one. One yuan polynomial addition, the system will prompt you to the importation of two polynomials information, and then calculate the two polynomials and guitar and output fruit polynomial. When users choose two. One yuan polynomial subtraction, the system will prompt you to the importation of two polynomials information, and then calculated the difference between the two polynomials and output polynomial. When users choose to withdraw, then returned to dos
