How to combine two different raster by replace its raster value at their overlap spac

[المشرف العام]

I have two different raster data :

• First data :
  
• Second data
  

How to combine those raster data? so the output data will be like this :



Where the overlap space between First data and second data (the green one) will contains the value of second data and the other will be refer to first data. So there will be two value in one raster data.A solution by using ArcGIS will be more preferable.
