3746.Escape from Stones

Time Limit: 1s Memory Limit: 256MB

Squirrel Liss lived in a forest peacefully, but unexpected trouble happens. Stones fall from a mountain. Initially Squirrel Liss occupies an interval [0,1]. Next, n stones will fall and Liss will escape from the stones. The stones are numbered from 1 to n in order.

The stones always fall to the center of Liss's interval. When Liss occupies the interval [k-d,k+d] and a stone falls to k, she will escape to the left or to the right. If she escapes to the left, her new interval will be [k-d,k]. If she escapes to the right, her new interval will be [k,k+d].

You are given a string s of length n. If the i-th character of s is "l" or "r", when the i-th stone falls Liss will escape to the left or to the right, respectively. Find the sequence of stones' numbers from left to right after all the n stones falls.

Input Format(From the terminal/stdin)

The input consists of only one line. The only line contains the string s (1 \le |s| \le 106). Each character in s will be either "l" or "r".

Output Format(To the terminal/stdout)

Output n lines - on the i-th line you should print the i-th stone's number from the left.
