An algorithm designed to find the mean of three values, xxx, yyy, and zzz, contains the instruction:
Mean←x+y+z/3 \text{Mean} \leftarrow x + y + z / 3 Mean←x+y+z/3The algorithm executes to completion without any system errors or crashes, but produces incorrect outputs.
Explain why this mistake is classified as a logic error rather than a syntax error.
