[ad_1] Woo, it’s been a long time since I dealt with C pointers, but let me see if I can help. Coordinate_T *p; declares a pointer to a Coordinate_T struct. We don’t have any memory available yet, we just have a pointer to… nothing. p = (Coordinate_T *)malloc(sizeof(Coordinate_T)) actually allocates the memory for us. Now … Read more
[ad_1] Computing the ratio Since there are multiple regions in a country, there are duplicated values in the Country_Region column. Therefore, I use groupby to sum the total cases of a nation. ratio = df.groupby(“Country_Region”)[[“Recovered”, “Confirmed”]].sum() ratio[“Ratio”] = ratio[“Recovered”] / ratio[“Confirmed”] Let’s get the first five nations. >>> ratio.head() Recovered Confirmed Ratio Country_Region Afghanistan 41727 … Read more
[ad_1] It’s not something I’d usually recommend but here’s a pretty hacky solution. const video = document.querySelector(“#video-element-id”); let tooSlow = false; let timeout = setTimeout(() => { tooSlow = true; …logic to change header clearTimeout(timeout); }, 1000); video.addEventListener(‘loadeddata’, () => { console.log(tooSlow ? ‘too slow’ : ‘loaded’); clearTimeout(timeout); }); * EDIT – or you could … Read more
[ad_1] If you already have the helper functions then you only need to loop once through each item of the list and modify all your key:value pairs: for i in list: i[‘key’] = recode_key(i[‘key’]) i[‘anotherkey’] = recode_anotherkey(i[‘key’]) i[‘yetanotherkey’] = recode_yetanotherkey(i[‘key’]) You would need to loop through the list once, touch all the keys that you … Read more

[ad_1] When you declare the object inside the loop, a new object will be created on each iteration and the exising one destroyed at the end of each iteration. This is because the object will have a scope inside the {}. When you declare it outside, a single object is created and you work with … Read more

[ad_1] Here char *firstName[50]; firstName is array of 50 character pointer, and if you want to store anything into each of these char pointer, you need to allocate memory for them. For e.g for (int counter = 0; counter < 10; counter ++) { firstName[counter] = malloc(SIZE_FIRST); /* memory allocated for firstName[counter], now you can … Read more
[ad_1] is_numeric only checks 1 variable. You have to write a if statement like the following: if(is_numeric($valortotal) && is_numeric($porcentagem1) && is_numeric($porcentagem2) && is_numeric($porcentagem3) && is_numeric($porcentagem4)) { echo “Por favor, digite apenas números”; } Note: This only echo’s “Por favor, digite apenas números” if all the variables are numeric.

[ad_1] You can make use of re.split to split into sections and then look for the [failed] string in the each section: splitted = re.split(r'(\d{1,2})\.(.*)(?= _{3,})’, text) failed = [(splitted[i-2], splitted[i-1]) for i, s in enumerate(splitted) if re.search(r’\[failed\]’, s)] failed # [(‘9’, ‘TX_MULTI_VERIFICATION 2412 DSSS-1 NON_HT BW-20 TX1′), # (’11’, ‘TX_MULTI_VERIFICATION 2472 DSSS-1 NON_HT BW-20 … Read more
[ad_1] First, use camelCase for naming in Swift. lowerCamelCase for constants/variables/functions and UpperCamelCase for types (classes, …) MAX_RADIUS_IN_MILE -> maxRadiusInMile Now to your problem. Error is clear, you have constant of type Double (if you don’t specify type of decimal number, compiler give it type Double), but assigning maximumValue requires type Float. What now? One … Read more

[ad_1] I being a number, there is 10 possibilities. S being a character, there is 26 possibilities. The total number of combinations is 10 power (TheNumberOfI) * 26 power (TheNumberOfS) This can be dynamically solved using a simple function that counts the number of S and the number of I and uses the results in … Read more
