Problem Statement
You are given a real-valued array containing exactly elements indexed from through . Traverse the array in increasing index order and select every element satisfying
Only selected elements are printed. Each printed value must have exactly one digit after the decimal point.
Input
The input contains exactly real numbers. Each value may be positive, negative, or zero.
Output
For each index satisfying , print A[i] = x, where has exactly one digit after the decimal point. Lines must be printed in increasing index order. If no element satisfies the condition, print nothing.
Subtasks
Subtask 1 (100 points): . This is the Phuoc Hung OJ data bound; the original selection rule and output format are unchanged.

Explanation
In the sample, indices contain , all at most . Every other value is greater than and is skipped. Therefore exactly those five lines are printed in increasing index order.
