This patch is to fix some minor typos in project. (#9852)

 Consider the above examples again. In order for InferBound to determine how many elements of C must be computed, it is important to know whether the computation of C occurs within the scope of a leaf variable of D, or above that scope. For example, in Ex. 1, the computation of C occurs  *above*  the scopes of all of D's leaf variables. In Ex. 2, the computation of C occurs  *within*  the scope of all of D's leaf variables. In Ex. 3, C occurs within the scope of D's i, but above the scope of D's j.
