You are given a string that represents an algebraic expression of the form a1 op .. op an, where-1016 a 1016 and "op" represents an operator in { +,-, Your task is to implement a function that "reverses" a given algebraic expression. For example, the reverse of the expression 100+200-300 would be 300-200+100 Input Format ). The input consists of one line that represents an algebraic expression. Constraints The operands can be integers or real numbers. The operators in the expression are +and/ There are no spaces in the expression. Each operand (a,) is between-1016 and 1016 (-101
