N M
a1 b1
a2 b2
... ...
an bn
は

ruby

N, M, *rest = $stdin.read.split
ABS = rest.each_slice(2).to_a

N T

c1 t1

c2 t2

cN tN

readlinesの場合

ruby

N, T = gets.split.map(&:to_i)
CTs = readlines.map{|l| l.split.map(&:to_i)}

ruby

z,*a=$<.map{|s|s.split.map &:to_i}

ruby

n,T=gets.split.map &:to_i;

さっぱりわかりません。
