题目描述

Levko loves array a1,a2,... ,ana_{1},a_{2},...\ ,a_{n} , consisting of integers, very much. That is why Levko is playing with array aa , performing all sorts of operations with it. Each operation Levko performs is of one of two types:

  1. Increase all elements from lil_{i} to rir_{i} by did_{i} . In other words, perform assignments aj=aj+dia_{j}=a_{j}+d_{i} for all jj that meet the inequation li<=j<=ril_{i}<=j<=r_{i} .
  2. Find the maximum of elements from lil_{i} to rir_{i} . That is, calculate the value .

Sadly, Levko has recently lost his array. Fortunately, Levko has records of all operations he has performed on array aa . Help Levko, given the operation records, find at least one suitable array. The results of all operations for the given array must coincide with the record results. Levko clearly remembers that all numbers in his array didn't exceed 10910^{9} in their absolute value, so he asks you to find such an array.

输入格式

The first line contains two integers nn and mm ( 1<=n,m<=50001<=n,m<=5000 ) — the size of the array and the number of operations in Levko's records, correspondingly.

Next mm lines describe the operations, the ii -th line describes the ii -th operation. The first integer in the ii -th line is integer tit_{i} ( 1<=ti<=21<=t_{i}<=2 ) that describes the operation type. If ti=1t_{i}=1 , then it is followed by three integers lil_{i} , rir_{i} and did_{i} ( 1<=li<=ri<=n1<=l_{i}<=r_{i}<=n , 104<=di<=104-10^{4}<=d_{i}<=10^{4} ) — the description of the operation of the first type. If ti=2t_{i}=2 , then it is followed by three integers lil_{i} , rir_{i} and mim_{i} ( 1<=li<=ri<=n1<=l_{i}<=r_{i}<=n , 5107<=mi<=5107-5·10^{7}<=m_{i}<=5·10^{7} ) — the description of the operation of the second type.

The operations are given in the order Levko performed them on his array.

输出格式

In the first line print "YES" (without the quotes), if the solution exists and "NO" (without the quotes) otherwise.

If the solution exists, then on the second line print nn integers a1,a2,... ,ana_{1},a_{2},...\ ,a_{n} (ai<=109)(|a_{i}|<=10^{9}) — the recovered array.
