Solution

Para resolver este problema, sigamos los siguientes pasos:

  1. Leer la entrada: Primero, necesitamos leer el nรบmero de casos de prueba t. Luego, para cada caso de prueba, leeremos el valor de n, el array a de longitud n y el array b de longitud n+1.

  2. Procesar cada caso de prueba:

    • Para cada caso de prueba, necesitamos encontrar la mรญnima cantidad de operaciones necesarias para transformar el array a en el array b.
    • Observamos que podemos copiar cualquier elemento de a y agregarlo al final de a para igualar la longitud de `b

You are given two arrays of integers a1,a2,โ€ฆ,an and b1,b2,โ€ฆ,bn. Before applying any operations, you can reorder the elements of each array as you wish. Then, in one operation, you will perform both of the following actions, if the arrays are not empty:1. Choose any element from array a and remove it (all remaining elements are shifted to a new array a)2. Choose any element from array b and remove it (all remaining elements are shifted to a new array b)Let k be the final size of both arrays.

Initially, we had one array, which was a permutation of size n๐‘› (an array of size n๐‘› where each integer from 11 to n๐‘› appears exactly once).We performed q๐‘ž operations. During the i๐‘–-th operation, we did the following:choose any array we have with at least 22 elements;split it into two non-empty arrays (prefix and suffix);write two integers li๐‘™๐‘– and ri๐‘Ÿ๐‘–, where li๐‘™๐‘– is the maximum element in the left part which we get after the split, and ri๐‘Ÿ๐‘– is the maximum element in the right part;remove the array we've chosen from the pool of arrays we can use, and add the two resulting parts into the pool.For example, suppose the initial array was [6,3,4,1,2,5][6,3,4,1,2,5], and we performed the following operations:choose the array [6,3,4,1,2,5][6,3,4,1,2,5] and split it into [6,3][6,3] and [4,1,2,5][4,1,2,5]. Then we write l1=6๐‘™1=6 and r1=5๐‘Ÿ1=5, and the arrays we have are [6,3][6,3] and [4,1,2,5][4,1,2,5];choose the array [4,1,2,5][4,1,2,5] and split it into [4,1,2][4,1,2] and [5][5]. Then we write l2=4๐‘™2=4 and r2=5๐‘Ÿ2=5, and the arrays we have are [6,3][6,3], [4,1,2][4,1,2] and [5][5];choose the array [4,1,2][4,1,2] and split it into [4][4] and [1,2][1,2]. Then we write l3=4๐‘™3=4 and r3=2๐‘Ÿ3=2, and the arrays we have are [6,3][6,3], [4][4], [1,2][1,2] and [5][5].You are given two integers n๐‘› and q๐‘ž, and two sequences [l1,l2,โ€ฆ,lq][๐‘™1,๐‘™2,โ€ฆ,๐‘™๐‘ž] and [r1,r2,โ€ฆ,rq][๐‘Ÿ1,๐‘Ÿ2,โ€ฆ,๐‘Ÿ๐‘ž]. A permutation of size n๐‘› is called valid if we can perform q๐‘ž operations and produce the given sequences [l1,l2,โ€ฆ,lq][๐‘™1,๐‘™2,โ€ฆ,๐‘™๐‘ž] and [r1,r2,โ€ฆ,rq][๐‘Ÿ1,๐‘Ÿ2,โ€ฆ,๐‘Ÿ๐‘ž].Calculate the number of valid permutations.InputThe first line contains two integers n๐‘› and q๐‘ž (1โ‰คq<nโ‰ค3โ‹…1051โ‰ค๐‘ž<๐‘›โ‰ค3โ‹…105).The second line contains q๐‘ž integers l1,l2,โ€ฆ,lq๐‘™1,๐‘™2,โ€ฆ,๐‘™๐‘ž (1โ‰คliโ‰คn1โ‰ค๐‘™๐‘–โ‰ค๐‘›).The third line contains q๐‘ž integers r1,r2,โ€ฆ,rq๐‘Ÿ1,๐‘Ÿ2,โ€ฆ,๐‘Ÿ๐‘ž (1โ‰คriโ‰คn1โ‰ค๐‘Ÿ๐‘–โ‰ค๐‘›).Additional constraint on the input: there exists at least one permutation which can produce the given sequences [l1,l2,โ€ฆ,lq][๐‘™1,๐‘™2,โ€ฆ,๐‘™๐‘ž] and [r1,r2,โ€ฆ,rq][๐‘Ÿ1,๐‘Ÿ2,โ€ฆ,๐‘Ÿ๐‘ž].OutputPrint one integer โ€” the number of valid permutations, taken modulo 998244353998244353.ExamplesinputCopy6 36 4 45 5 2outputCopy30inputCopy10 1109outputCopy1814400inputCopy4 124outputCopy8
