Score : 400400 points

Problem Statement

There are NN ropes numbered 11 through NN. One end of each rope is painted red, and the other is painted blue.

You are going to perform MM operations of tying ropes. In the ii-th operation, you tie the end of rope AiA_i painted BiB_i with the end of rope CiC_i painted DiD_i, where R means red and B means blue. For each rope, an end with the same color is not tied multiple times.

Find the number of groups of connected ropes that form cycles, and the number of those that do not, after all the operations.

Here, a group of connected ropes {v0,v1,,vx1}\lbrace v_0, v_1, \ldots, v_{x-1} \rbrace is said to form a cycle if one can rearrange the elements of vv so that, for each 0i<x0 \leq i < x, rope viv_i is tied to rope v(i+1)modxv_{(i+1) \bmod x}.

Constraints

  • 1N2×1051 \leq N \leq 2 \times 10^5
  • 0M2×1050 \leq M \leq 2 \times 10^5
  • 1Ai,CiN1 \leq A_i, C_i \leq N
  • $(A_i, B_i) \neq (A_j, B_j), (C_i, D_i) \neq (C_j, D_j)$ (ij)(i \neq j)
  • (Ai,Bi)(Cj,Dj)(A_i, B_i) \neq (C_j, D_j)
  • N,M,AiN, M, A_i, and CiC_i are integers.
  • BiB_i is R or B, and so is DiD_i.

Input

The input is given from Standard Input in the following format:

NN MM

A1A_1 B1B_1 C1C_1 D1D_1

A2A_2 B2B_2 C2C_2 D2D_2

\vdots

AMA_M BMB_M CMC_M DMD_M

Output

Print XX and YY in this order, separated by a space, where XX is the number of groups of connected ropes that form cycles, and YY is the number of those that do not.

There are three groups of connected ropes: {1}\lbrace 1 \rbrace, {2,4}\lbrace 2,4 \rbrace, and {3,5}\lbrace 3,5 \rbrace.

The group of ropes {3,5}\lbrace 3,5 \rbrace forms a cycle, while the groups of rope {1}\lbrace 1 \rbrace and ropes {2,4}\lbrace 2,4 \rbrace do not. Thus, X=1X = 1 and Y=2Y = 2.
