E Minimum Array (二分+multiset) ( Codeforces Round #555 (Div. 3) )
You are given two arrays aa and bb, both of length nn. All elements of both arrays are from 00 to n−1n−1.
You can reorder elements of the array bb (if you want, you may leave the order of elements as it is). After that, let array cc be the array of length nn, the ii-th element of this array is ci=(ai+bi)%nci=(ai+bi)%n, where x%yx%y is xx modulo yy.
Your task is to reorder elements of the array bb to obtain the lexicographicallyminimum possible array cc.
Array xx of length nn is lexicographically less than array yy of length nn, if there exists such ii (1≤i≤n1≤i≤n), that xi<yixi<yi, and for any jj (1≤j<i1≤j<i) xj=yjxj=yj.
Input
The first line of the input contains one integer nn (1≤n≤2⋅1051≤n≤2⋅105) — the number of elements in aa, bb and cc.
The second line of the input contains nn integers a1,a2,…,ana1,a2,…,an (0≤ai<n0≤ai<n), where aiaiis the ii-th element of aa.
The third line of the input contains nn integers b1,b2,…,bnb1,b2,…,bn (0≤bi<n0≤bi<n), where bibi is the ii-th element of bb.
Output
Print the lexicographically minimum possible array cc. Recall that your task is to reorder elements of the array bb and obtain the lexicographically minimum possible array cc, where the ii-th element of cc is ci=(ai+bi)%nci=(ai+bi)%n.
