A dockyard keeps a manifest of n cargo tags, each tag written as a lowercase string. Safety inspectors are checking every tag for one specific hazard letter c; any tag whose characters include c at least once must be flagged for inspection. Given the manifest, report — in the exact order the tags were logged — the 0-indexed positions of every tag that contains the hazard letter c.

Input format

• Line 1: a single integer n.
• Line 2: a single lowercase English letter c, the hazard letter.
• Next n lines: the manifest, one cargo tag per line; each tag is a non-empty string of lowercase English letters.

Output format

• A single line listing the 0-indexed positions of every tag containing c, separated by single spaces, in increasing order. If no tag contains c, print an empty line.

Constraints

• 1 <= n <= 50
• 1 <= length of each tag <= 50
• c and every tag consist only of lowercase English letters ('a'-'z').
