RLE$($Run Length Encoding$)$ is a data compression technique where data is compressed to store data value and the number of times it is repeated. For example, the following is the technique to represent white text on a black background: B $=$ black pixel and W $=$ white pixel BBBBBBWBBBBWWWBBB RLE data compression renders the above as $6$B$1$W$4$B$3$W$3$B which is interpreted as a sequence of six Bs$,$one W$,$ four Bs$,3$Ws$,$etc. Which of the following is true about RLE?
