WebMar 6, 2024 · The idea of the Binary Lifting algorithm is that we reduce the number of upward jumps and hence reduce the number of comparisons. In the brute force approach, we were making the jumps of one unit upwards and then comparing the values of both nodes, but now we’ll lift the nodes in the power of twos.
