Let g = (v, e) be a flow network with source s, sink t, and integer capacities. we assume that we are given a maximum flow in g.
(a) suppose we increase the capacity of single edge (u, v) ∈ e by 1. prove that one iteration of the ford-fulkerson algorithm is sufficient to update the maximum flow.
(b) suppose we decrease the capacity of single edge (u, v) ∈ e by 1. prove that one iteration of the ford-fulkerson algorithm is sufficient to update the maximum flow.

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.

Anul 2017 tocmai s-a încheiat, suntem trişti deoarece era număr prim, însă avem şi o veste bună, anul 2018 este produs de două numere prime, 2 şi 1009. dorel, un adevărat colecţionar de numere prime, şi-a pus întrebarea: “câte numere dintr-un interval [a,b] se pot scrie ca produs de două numere prime? “.
