Gene expression measurements

We have done some experiments measuring the expression of several genes in a population subjected to a genetic therapy. For each gene, we have the measurement of its expression in the control population, and in the treated population. Write a program that computes the change recorded for each gene between both populations, and reports whether the gene is upregulated (positive change), downregulated (negative change), or presents no change. Finally, the program should report which gene suffered the largest change (either positive or negative). In case of a tie, report the first such gene found in the input.

Input

The input is a sequence of triplets. Each triplet consists of a string (gene name) and two real numbers: the expression in the control population and the expression in the treated population.

Output

The output is the value of the change in expression for each gene, and whether it is up- or down- regulated. At the end, the gene with largest change is reported. Follow the format of the examples.

Observation

Remember that to print a real number x with two decimal digits, you can use f"x:.2f"
