B"Recently, Vladimir got bad mark in algebra again. To avoid such unpleasant events in future he decided to train his arithmetic skills. He wrote four integer numbers a, b, c, d on the blackboard. During each of the next three minutes he took two numbers from the blackboard (not necessarily adjacent) and replaced them with their sum or their product. In the end he got one number. Unfortunately, due to the awful memory he forgot that number, but he remembers four original numbers, sequence of the operations and his surprise because of the very small result. Help Vladimir remember the forgotten number: find the smallest number that can be obtained from the original numbers by the given sequence of operations. First line contains four integers separated by space: 0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89a, xe2 x80 x89b, xe2 x80 x89c, xe2 x80 x89d xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891000 -- the original numbers. Second line contains three signs ('+' or '*' each) separated by space -- the sequence of the operations in the order of performing. ('+' stands for addition, '*' -- multiplication) Output one integer number -- the minimal result which can be obtained. Please, do not use %lld specificator to read or write 64-bit integers in C++. It is preffered to use cin (also you may use %I64d)."...
