QUESTION
I am creating a dictionary with "Full Name": "Birthday" for numerous people as an exercise. The program should ask "Who's birthday do you want to look up?" I will input a name, say "Benjamin Franklin" And it will return his birthday: 1706/01/17.
Alright, the problem I am encountering is name capitalization. How can I input "benjamin franklin" and still find "Benjamin Franklin" in my dictionary? I am familiar with .lower() and .upper() functions, however I am not able to implement them correctly, is that the right way to approach this problem?
Here is what I have

Hey just doing some exercises in c, one is saying to replace tabs in the input string with any other characters , i restrict myself to only using getchar(), no gets() fgets() etc..., as my learning book didn't catch it yet, so i tried to not break the flow, the code below just printf() the same line it receives, can you please examine why ?
ANSWER
Answered 2021-Jun-15 at 16:33c, which is used inc != '\n', is not initialized at first. Its initial value is indeterminate and using is value without initializng invokes undefined behavior.- You are checking
line[i] != '\0', but you never assigned'\0'tolineunless'\0'is read from the stream. - You should initialize
ibefore the second loop and updateiduring the second loop. - Return values of
getchar()should be assigned tointto distinguish betweenEOFand an valid character. - You should perform index check not to cause buffer overrun.

QUESTION
I'm trying to solve an exercise in vanilla JS but can't figure out what I am doing wrong. I would like to change to color text to red if the product price is > 300.
In the console.log I'm getting all ok but on changeColor.style.color = "red"; I'm getting this error: TypeError: Cannot set property 'color' of undefined
Also because the page has a lazy load I could I get all price change by the time you are scrolling down?
Thanks
...ANSWER
Answered 2021-Jun-15 at 14:40 var offer = document.querySelectorAll(".grocery-item__normal-price");
var price = document.querySelectorAll(".grocery-item__normal-price");
let changePriceColor = 300;
price.forEach( (price) => {
var changeColor = price.innerHTML.slice(0,4).replace(/,/g, '');
if( changeColor > changePriceColor ) {
price.style.color = "red";
console.log(price, "true");
} else {
console.log(changeColor, "false")
}
})

QUESTION
I'm having a problem with altering the value of a mutable map. I assume it's something to do with nullable types, but I'm not sure. The code producing the error is below:
...ANSWER
Answered 2021-Jun-15 at 08:46The statement map.getValue(num) += 1 is not allowed because the += operator is only defined in 2 cases:
- a plusAssign() operator is defined on the left operand's type (not the case for
Int) - a plus() operator is defined on the left operand's type AND the left operand is a variable. In this case
+=reassigns the variable on the left witholdValue.plus(the right operand).
The compiler tries to consider case #2 here because Int.plus(Int) is defined, but the left operand is not a variable so it fails with the error message you mentioned.
You can't write this for the same reasons you can't write map.getValue(num) = 42.
The correct way of mutating a value in a map is either via the set operator (like you did earlier with the syntax sugar map[num] = 0), or via other mutating functions like merge.
In your case, merge is nice because it can remove the special case altogether (it's only available on the JVM target though):

QUESTION
I'm going through this MIT Intro to Comp Sci Using Python course on Edx. There is an exercise telling us to use bisection search and recursion to check if a character is in an alphabetically ordered string. For some reason, I got a syntax error when I put the variable HALF after that If-statement, while I won't get an error if I declare it before the If-statement. All I could find is not being able to declare local variables in an If-statement. Please tell me or refer me to websites explaining why this happens? Thanks a bunch.
Here's the code:

...ANSWER
Answered 2021-Jun-14 at 01:04CloudFormation (CFN) is not going to take your chaklader.pem and create a pair key in AWS. You have to do it before hand yourself. And you can't use CFN for that as it is not supported, unless you will program such a logic yourself using custom resource.
The easiest way is to create or import the key "manually" using AWS Console, SDK or CLI. Then you can reference its name in your template.
