Strings batch$1,$ batch$2,$ and batch$3$ are read from input. Each string represents a list of color$($s$)$ surrounded by $"\{"$ and $"\}".$

Assign combinedColors with the concatenation of batch$1,$ batch$2,$ and batch$3$ in the order read.

Assign mergedList with a string that contains all the color$($s$)$ in batch$1,$ batch$2,$ and batch$3$ in the order read, separated by $""$ and surrounded by $"\{"$ and $"\}".$

Ex: If the input is:

$\{$ochre$\}$

$\{$magenta$\}$

$\{$blue$\}$

then the output is:

All batches in one line: $\{$ochre$\}\{$magenta$\}\{$blue$\}$

One batch of all colors: $\{$ochre magenta blue$\}$
