For example, consider the green line. What is its length? In $L_2$, the answer is $1$, in $L_1$, the answer is $1$ as well. Now, for the same line, let's rotate it $45^\circ$ counterclockwise. What is the length again? In $L_2$, its length remains to be $1$. However, in $L_1$, using Manhattan distance, it's length is now $\frac{1}{\sqrt{2}}+\frac{1}{\sqrt{... 1 Actually this is the Manhattan /$L_1$/ Norm 1 distance, if you just multiply the row by$8$(or$N$). The$L_1$distance between$[24, 2]$and$[32, 5]\$ is what you are looking for.
