Hi everyone,
I’m working on a problem where my solution isn’t getting Accepted (AC), and I’m struggling to figure out why. The time limit is 3 seconds so ideally even n^2 should pass . As far as I think my code is somewhat around O(n+mlogm) . Problem Link
Looking for positive response :) submission id --> 299093047 My code
If I am not wrong. I think
vector< vector<int> > p ( 2e5+2 );is a bit slow. Creating and destryoying these many elements.Yes you are correct . It was an unnecessary overhead and I wasn't using most of the indexes just iterating without any need over them . I shifted to map to sort of create an adjacency list to solve this . Also I thought after each jump the powerup of sharky fades away. But no that wasn't the case . Once you consume a powerup jump power is increased and is persistent. Question should have specified this .MY AC CODE
Tanks for your reply.
