: the character '90', the character '%', the interval between two characters, and the square area where the two characters are located. The size of each region has been described in the figure. Our task is to calculate the left and bottom coordinate points (Xn, yn) and (XP, YP) of two characters ). Based on the description in the figure, we can easily use the following formula to calculate the two coordinates: half of the width of the character and its interval: offset = (Wn + WP + DH) /2xn = W/

He did not like the order of the trees, for they were so uneven in height and height. FGD defines the degree of ataxia of these trees as well as the height difference of the two adjacent trees. The height of the tree was H1,h2,h3,..., HN
