Counting With Code Examples

Good day, guys. In this put up, we’ll take a look at the way to resolve the Counting programming puzzle.

```"""Find all occurrences of ingredient in record"""

# If you merely need discover what number of occasions a component seems
# use the built-in perform rely()
def find_occur(lst, merchandise):
return lst.rely(merchandise)

# Test -----------------------------------------------------------
print(find_occur([None, None, 1, 2, 3, 4, 5], None)) # 2

# If you wanna discover the place they happen as a substitute
# - This returns the indices the place ingredient is discovered inside a listing

def discover(lst, merchandise):
return [i for (i, x) in enumerate(lst) if x == item]

# Test Code ------------------------------------------------------
from random import randint, alternative
lst = [randint(0, 99) for x in range(10)] # random lst
merchandise = alternative(lst) # merchandise to search out
discovered = discover(lst, merchandise) # lst of the place merchandise is discovered at
print(f"lst: {lst}",
f"merchandise: {merchandise}",
f"discovered: {discovered}",
sep = "n")```

Another methodology that’s described under with code examples can be utilized to sort out the identical concern Counting.

```let n=0
set n=n+1```
```	//Calculate the occasions a personality happens
public static int charCount(String personInput) {

//convert the string to a char array
char[] StringArray = personInput.toCharArray();

//hashmap that shops the characters. key would be the time it occures
HashMap<Character, Integer>charCount = new HashMap<Character, Integer>();```

We investigated a variety of use instances with the intention to discover a resolution to the Counting drawback.
