pqstr
Se dau două numere naturale P
şi Q
şi un şir S
= S[1]
, S[2]
, …, S[N]
de numere întregi. Din şirul S
trebuie ales un (P,Q)-subşir S[i
1
]
, S[i
2
]
, …, S[i
k
]
astfel încât k ≥ 2
și P ≤ i
j
– i
j-1
≤ Q
pentru orice j=2..k
.
De exemplu, pentru P=2
, Q=3
şi S=(2,-3,-7,-8,5,-1)
, subşirul (2,-3,-8)
nu este (2,3)-subşir
, dar subşirurile (2,-7,5)
și (2,-7,-1)
sunt (2,3)-subşiruri
.
Pentru orice (P,Q)-subşir X = (S[i1
1
],S[i
2
], ...,S[i
r
])
, ne interesează valoarea expresiei
e(X) = |S[i
1
] - S[i
2
]| + |S[i
2
] - S[i
3
]| + ... + |S[i
r-1
] - S[i
r
]|
unde cu |a|
s-a notat modulul numărului întreg a
.
Să se calculeze şi să se afişeze E = max{e(X), X este (P,Q)-subşir al lui S}
.
