 Define $\texttt{dp}[i][j]$ as the minimum number of paintings to paint the range
 $[i, j]$. Then, one of two things can happen when combining ranges
-$[i, j], [j + 1][k]$:
+$[i, j], [j + 1, k]$:
 
 1. $A[i] == A[k]$. This means that the range $[i, k]$ has a common color for each
    endpoint. Therefore, we can "save" a color when merging the two ranges.
