Summary

Read n bar sizes and print one line of exactly k equals signs for each bar size k.

Problem

A histogram is a picture of data. It is made of bars, and the length of one bar is the size of the data it stands for.

You are given a list of bar lengths. Draw the histogram for that list.

The first line contains the number of test cases $n$ ( $1 \le n \le 100$ ).

Each of the next $n$ lines contains the size $k$ ( $1 \le k \le 80$ ) of one histogram bar.

For each test case, print one line holding exactly $k$ copies of =, where $k$ is that bar's size. Do not put a space between two = characters.
