🔒 How to get number from Json string and get closest number below given number?

[ripe glacier]

If I have Json below:

{
"ScriptMethod": [
{
"Address": 10000000,
"Name": "Interop.ErrorInfo$$.ctor",
"Signature": "void Interop_ErrorInfo___ctor (Interop_ErrorInfo_o __this, int32_t errno, const MethodInfo* method);",
"TypeSignature": "viii"
},
{
"Address": 20000000,
"Name": "Interop.ErrorInfo$$.ctor",
"Signature": "void Interop_ErrorInfo___ctor (Interop_ErrorInfo_o __this, int32_t error, const MethodInfo* method);",
"TypeSignature": "viii"
},
{
"Address": 30000000,
"Name": "Interop.ErrorInfo$$get_Error",
"Signature": "int32_t Interop_ErrorInfo__get_Error (Interop_ErrorInfo_o __this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 40000000,
"Name": "Interop.ErrorInfo$$get_RawErrno",
"Signature": "int32_t Interop_ErrorInfo__get_RawErrno (Interop_ErrorInfo_o __this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 50000000,
"Name": "Interop.ErrorInfo$$GetErrorMessage",
"Signature": "System_String_o* Interop_ErrorInfo__GetErrorMessage (Interop_ErrorInfo_o __this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 60000000,
"Name": "Interop.ErrorInfo$$ToString",
"Signature": "System_String_o* Interop_ErrorInfo__ToString (Interop_ErrorInfo_o __this, const MethodInfo* method);",
"TypeSignature": "iii"
}
}
}

How can I get Address above as a List or Array or anything, then
If I have given number 33000000

How can I compare my given number with the list of Address, then find closest number below my given number

I mean, I want the result to be 30000000

If you keep it sorted, then you could do a binary search, then at the end either you find an exact match, and use that, or you just calculate the abs difference between the target and left/right node, pick whichever one is closer

Otherwise you could also just loop through each one, calculate the abs difference between the target and the element you're checking, and store the minimum difference along with the index

Then just access that index

what code or command or function should I use to get the address as a list or array?

then, is it possible to do like this below?

myArr[myArr < myNumber].max()

[indigo belfry]

wdym as a list or array?

[zenith dragon]

!e ```py
def func(values, target):
return max(sorted(v for v in values if v < target)) # <= ?

json_data = {
"ScriptMethod": [
{
"Address": 10000000,
"Name": "Interop.ErrorInfo$$.ctor",
"Signature": "void Interop_ErrorInfo_ctor (Interop_ErrorInfo_o this, int32_t errno, const MethodInfo* method);",
"TypeSignature": "viii"
},
{
"Address": 20000000,
"Name": "Interop.ErrorInfo$$.ctor",
"Signature": "void Interop_ErrorInfo_ctor (Interop_ErrorInfo_o this, int32_t error, const MethodInfo* method);",
"TypeSignature": "viii"
},
{
"Address": 30000000,
"Name": "Interop.ErrorInfo$$get_Error",
"Signature": "int32_t Interop_ErrorInfoget_Error (Interop_ErrorInfo_o this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 40000000,
"Name": "Interop.ErrorInfo$$get_RawErrno",
"Signature": "int32_t Interop_ErrorInfoget_RawErrno (Interop_ErrorInfo_o this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 50000000,
"Name": "Interop.ErrorInfo$$GetErrorMessage",
"Signature": "System_String_o* Interop_ErrorInfoGetErrorMessage (Interop_ErrorInfo_o this, const MethodInfo* method);",
"TypeSignature": "iii"
},
{
"Address": 60000000,
"Name": "Interop.ErrorInfo$$ToString",
"Signature": "System_String_o* Interop_ErrorInfoToString (Interop_ErrorInfo_o this, const MethodInfo* method);",
"TypeSignature": "iii"}
]
}

values = [d['Address'] for d in json_data['ScriptMethod']]

result = func(values, 33000000)
print(result)```

@ripe glacierSomething along these lines?

Actually...I don't know why I sorted it.

I was thinking of something else.

Hang on.

It still works, it's just...extra.

@zenith dragon
Wow, Thank You

Ok, I'm waiting

[zenith dragon]

So you definitely want the value that's lower than the target, not lower to or equal to the target?

!e ```py
def func(values, target):
return max(v for v in values if v < target)

result = func([1, 3, 5], 3)
print(result)```

vs

!e ```py
def func(values, target):
return max(v for v in values if v <= target)

result = func([1, 3, 5], 3)
print(result)```
