Topic
Implement a basic calculator to evaluate a simple expression string.
The expression string contains only non-negative integers,,, + - * , / operators and empty spaces . The integer division should truncate toward zero.
Assume that the given expression was always valid.
Some Examples:
"3+2*2" = 7 "3/2" = 1 "3+5/2" = 5
A calculator
left is the logarithm, the right is the exponent, close to the target one step, but still not calculate. Turn the exponential into a radical with some black technology:\ (Ln{a} = \lim_{x\rightarrow 0}\frac{a^{x}-1}{x} \)\ (= \lim_{k\rightarrow +\infty}\frac{a^{(2^{-k})}-1}{(2^{-k})} \)\ (= \lim_{k\rightarrow +\infty} (A^{\frac{1}{2^{k}}-1) \cdot 2^{k} \)\ (= \lim_{k\rightarrow +\infty} (\sqrt[2^k]{a}-1) \cdot 2^{k} \)\ (= \lim_{k\rightarrow +\infty} (\underbrace{\sqrt{\cdots\sqrt{\sqrt{a}}}}_{k
