Raster data RECLASSIFICATION in QGIS 3

Reclassification is the process of reassigning one or more values in a raster dataset to new output values.
This could be due to finding out that the value of a cell should actually be a different value, for example, the land use in an area changed over time.
Let's see how to do a data reclassification in QGIS.
