count apples and oranges

/**
 * count apples and oranges whether land on the inclusive [s,t]
 * a is apple tree's cordination, b is orange tree's corditation
 * apples is apple tree's relative cordination ,left relative apple tree is represention by negative value
 * right relative is represention by positive value
 * oranges is same as apples
 * constrant condition :
 * 1<=s,t,a,b,m,n<=10to5 m is apples' size, n is oranges' size
 * -10to5<=d<=10to5 d is apples' cordation plus a's cordation and generate out donation distance and compute oranges' d as well
 * a<s<t<b
 * @param s
 * @param t
 * @param a
 * @param b
 * @param apples
 * @param oranges
