Answer:

Run-length encoding is a data compression calculation that is upheld by most bitmap file formats, for example, TIFF, BMP, and PCX. RLE is suited for compressing any kind of data paying little mind to its information content, yet the substance of the data will influence the compression proportion accomplished by RLE. Albeit most RLE algorithms can't accomplish the high compression proportions of the further developed compression strategies, RLE is both simple to actualize and brisk to execute, making it a decent contrasting option to either utilizing a mind boggling compression calculation or leaving your picture data uncompressed.

RLE works by lessening the physical size of a rehashing series of characters. This rehashing string, called a run, is commonly encoded into two bytes. The main byte speaks to the quantity of characters in the run and is known as the run check. By and by, an encoded run may contain 1 to 128 or 256 characters; the run consider for the most part contains the quantity of characters short one (an incentive in the scope of 0 to 127 or 255). The second byte is the estimation of the character in the run, which is in the scope of 0 to 255, and is known as the run esteem.
