题目描述

Andrewid the Android is a galaxy-famous detective. He is now chasing a criminal hiding on the planet Oxa-5, the planet almost fully covered with water.

The only dry land there is an archipelago of nn narrow islands located in a row. For more comfort let's represent them as non-intersecting segments on a straight line: island ii has coordinates [li,ri][l_{i},r_{i}] , besides, r_{i}<l_{i+1} for 1<=i<=n11<=i<=n-1 .

To reach the goal, Andrewid needs to place a bridge between each pair of adjacent islands. A bridge of length aa can be placed between the ii -th and the (i+1)(i+1) -th islads, if there are such coordinates of xx and yy , that li<=x<=ril_{i}<=x<=r_{i} , li+1<=y<=ri+1l_{i+1}<=y<=r_{i+1} and yx=ay-x=a .

The detective was supplied with mm bridges, each bridge can be used at most once. Help him determine whether the bridges he got are enough to connect each pair of adjacent islands.

输入格式

The first line contains integers nn ( 2<=n<=21052<=n<=2·10^{5} ) and mm ( 1<=m<=21051<=m<=2·10^{5} ) — the number of islands and bridges.

Next nn lines each contain two integers lil_{i} and rir_{i} ( 1<=li<=ri<=10181<=l_{i}<=r_{i}<=10^{18} ) — the coordinates of the island endpoints.

The last line contains mm integer numbers a1,a2,...,ama_{1},a_{2},...,a_{m} ( 1<=ai<=10181<=a_{i}<=10^{18} ) — the lengths of the bridges that Andrewid got.

输出格式

If it is impossible to place a bridge between each pair of adjacent islands in the required manner, print on a single line "No" (without the quotes), otherwise print in the first line "Yes" (without the quotes), and in the second line print n1n-1 numbers b1,b2,...,bn1b_{1},b_{2},...,b_{n-1} , which mean that between islands ii and i+1i+1 there must be used a bridge number bib_{i} .

If there are multiple correct answers, print any of them. Note that in this problem it is necessary to print "Yes" and "No" in correct case.

说明/提示

In the first sample test you can, for example, place the second bridge between points 3 and 8, place the third bridge between points 7 and 10 and place the first bridge between points 10 and 14.

In the second sample test the first bridge is too short and the second bridge is too long, so the solution doesn't exist.
