.Verification successful
Function
fn1
is only used in the test file and does not impact the main codebase's performance.
- The function
fn1
is only found intest/test_lazy.cpp

.Verification successful
Verify the impact of the updated constant
N
.The constant
N
has been updated from1e6
to1e6 + 5
. The change is minor and is unlikely to negatively impact performance or outcomes in functions that rely onN
.
- The constant
N
is used intest/test_lazy.cpp
for initializing vectors and performing various operations.- The increase in size by 5 elements is relatively minor.
