## What is the RAM frequency of my laptop?

The prompt displays 2667MHz. Task Manager says 2400MHz. CPU-Z varies the DRAM frequency from 933 MHz to 1200 MHz (should stay at 1200 MHz, right?) And UserBenchmark indicated that 8 GB SODIMM DDR4 2667 MHz are clocked at 2400 MHz.

I want to buy another module, so I have to know the right frequency.

## Converts the histogram by the frequency of the string length in percent

I have the histogram:

```dataPnJ = StringLength[ StringSplit[ExampleData[{"Text", "PrideAndPrejudice"}]]]; Histogram[dataPnJ]```

I'm trying to show the histogram what percentage of the total pool is the string length. So if 30% of the text consists of 3 letters, the bin is marked 3 and raised to 30%.
Thanks.

## Data Structures – Given node and given value determine the frequency of the given value from node to root in a tree

A tree with `N` Vertices and `N-1` Edges is present.

A value `x` can be inserted in each of the nodes.

A single node can contain multiple values.

How do I answer inquiries of the specified type?

Given a knot `n` and value `v` Find the frequency of `v` on the way from the knot `n` to the root of the tree.

## Mobile Network – Can Android KitKat be bound to a specific frequency / band in any way?

Usually we can set our mobile phone in the setting to either LTE, WCDMA or GSM mode. But I want to lock specifically the 900MHz and / or 1800MHz band, which they contain as GSM in Network Mode. Then my question is: is there a way to do this? Preferably, if I can only execute commands or scripts without installing an application. But even a thorough application is fine.

## c – Determine the frequency of unique array elements using a single pointer

I am supposed to find the frequency of the unique array elements of a character array via a user-defined function int * unique (char * s)that takes a pointer to a character and returns a pointer to a dynamically assigned array of integers.

There are some limitations. I can not use an extra array or array indexing. Only pointer arithmetic is allowed. My solution is as follows:

`````` int *uniqueCount(char *s)
{
int a=0,k,p;
for(k=0;*(s+k);k++)
{
for(p=k+1;*(s+p);p++)
{
if(*(s+k)==*(s+p)) break;
}
if(*(s+p)==0) a++;
}
int *arr,i=0;
arr=malloc(sizeof(int)*a);
for(k=0;*(s+k);k++)
{
*(arr+i)=1;
for(p=k+1;*(s+p);p++)
{
if(*(s+k)!='*'&&*(s+k)==*(s+p)){
*(s+p)='*';
*(arr+i)+=1;
}
}
if(i``````
``` Some problems that I face with my function: (I) Use of the function in an actual program, eg. Receiving the returned integer pointer and printing values. (Ii) I change the array element in "*" in the second part of the function. I want to avoid it. I know that I have made a complex function difficult to understand. If there is an optimized and simpler solution, this would be helpful. Thank you very much... ```

Next to a laptop I use a radio frequency (RF) board to implement a software-defined radio function (eg virtual eNode-B or gNode-B) with a small plug-in omnidirectional antenna. Would that be a problem when transferring to an airport when stowed in hand luggage with a laptop? For information: It is a USRP of Ettus Research Group of National Instruments.
