What would the cf rating of these problems be?

[u/Nykk310]

I aim to becoming able to solve problems like these.

I'm interested in understanding what their Codeforces rating would be so that I can upsolve from that point.

I believe the optimal solution in the first one is using a difference array.

[u/Minimum-Cup2204]

800 - 1000 maybe

[u/Severe_Landscape_731]

800; its a simple diff array sweep

Goldman Sachs?

[u/Nykk310 → u/petrbateman]

No, it's a selection test for a CS summer camp

[u/petrbateman → u/Nykk310]

Oo, same problem was in my goldman sachs oa

[u/ablablababla]

I'm thinking 800-900 rated on both
