解题思路:给出一个方程 8*x^4 + 7*x^3 + 2*x^2 + 3*x + 6 == Y,求方程的解. 首先判断方程是否有解,因为该函数在实数范围内是连续的,所以只需使y的值满足f(0)<=y<=f(100),就一定能找到该方程的解,否则就无解. 然后是求解过程, 假设一个区间[a,b],mid=(a+b)/2,如果f(a)*f(b)<0,那么函数f(x)在区间[a,b]至少存在一个零点,如果f(a)<0,说明0点在其右侧,那么将a的值更新为当前mid的值,如果f(a)&g…

题目如下: 解题思路:本题的思路就是解析字符串,然后是小学时候学的解方程的思想,以"2x+3x-6x+1=x+2",先把左右两边的x项和非x项进行合并,得到"-x+1=x+2",接下来就是移项,把x项移到左边,常数项移到右边,得到"2x=-1",最后的解就是x=-1/2.对于任意一个表达式ax+b = cx+d来说,最终都能得到解x=(d-b)/(a-c),这里要对(a-c)是否为0做判断,同时根据(d-b)是否为0等到Infinite solu…
