For two strings $A$ and $B$, let $A+B$ denote the concatenation of $A$ and $B$ in this order. You are given $N$ strings $S_1,\ldots,S_N$. Modify and print them as follows, in the order $i=1, \ldots, N$: * if none of $S_1,\ldots,S_{i-1}$ is equal to $S_i$, print $S_i$; * if $X$ $(X>0)$ of $S_1,\ldots,S_{i-1}$ are equal to $S_i$, print $S_i+$ `(` $+X+$ `)`, treating $X$ as a string. ## Constraints * $1 \leq N \leq 2\times 10^5$ * $S_i$ is a string of length between $1$ and $10$ (inclusive) consisting of lowercase English letters. ## Input Input is given from Standard Input in the following format: $N$ $S_1$ $S_2$ $\vdots$ $S_N$ [samples]
