Dijkstra’s algorithm is one of the most popular algorithms for solving many single-source shortest path problems having non-negative edge weight in the graphs i.e., it is to find the shortest distance between two vertices on a graph. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later.

WebThree Matrices can be multiplied in two ways: A1, (A2,A3): First multiplying (A 2 and A 3) then multiplying and resultant withA 1. (A1,A2),A3: First multiplying (A 1 and A 2) then multiplying and resultant withA 3. No of Scalar multiplication in Case 1 will be: (100 x 5 x 50) + (10 x 100 x 50) = 25000 + 50000 = 75000. inbouw radiator
