Candlesticks are a common visualisation used to show the trends in a trading system. The candlesticks show what happens in a series of time windows, in terms of the starting price, the end price and the highest and lowest prices seen. The following image shows a graphical plot of candlestick data:

Figure $1$: example of a graphical candlestick plot. Each box represents the trading activity in a time period. The top and bottom of a box $($the candle$)$ represent the opening and closing value of a product. The top and bottom of the lines $($the candlesticks$)$ represent the highest and lowest value seen in that time frame. The red box on May $3$rd indicates the value was lower at close than open, so value went down. You do not need to make a graphical plot $$ you will be making a text based plot.

In the first task, you need to compute candlestick data from the exchange data for a particular product. Close: the average price per unit in this time frame $($same as Open, but for the current time frame$)$

High: highest price seen this time frame

Low: lowest price seen this time frame

You should implement the candlestick data computation using a function which returns the following data type:

std::vector

Note that it returns a vector of Candlestick objects. You will need to define your own Candlestick class that is suitable for representing candlestick data. One Candlestick object represents one candlestick.
