Matrix Chain MultiplicationSuppose you has to evaluate a expression like a*b*c*d*e where a,b,c,d and E is matrices. Since matrix multiplication is associative, the order of which multiplications is performed. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.For example, let A is a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There is different strategies to compute a*b*c, namely (A*B) *c and a A * (B*C).The first one takes 15000

Give the N,m,wi,di, beg M.A very standard 01 knapsack problem. Code that uses an optimized one-dimensional array. Because for this kind of problem, only I-1 's f[v] is useful for calculating the f[v of I, so using a one-dimensional array is equivalent to overwriting the previous record before i-1.Below is my
