line 51, there is a error

}while(opStack.length>0 && op>operatorPrivilege(opStack[opStack.length-1]) && opStack[opStack.length-1]!='(');

the second condition : op>operatorPrivilege(opStack[opStack.length-1])

should be op<=operatorPrivilege(opStack[opStack.length-1])

sad, stupid random test.

how to solve this problem?
