Is there any series of videos in which all the main algorithms are discussed without going into things like time complexity and space complexity
Your question doesn't make much sense. First, there are literally thousands of major algorithms, and many of them are quite involved. You don't begin your studies with Red-Black Trees because even their purpose will elude you until you've (at the very least) spent some time dealing with sorts and searches.

Second, if you eliminate time complexity and the actual steps to make an algorithm possible, what is left? A vague discussion of the purpose of the algorithm? Needless to say, no such discussion would include any bits of actual programming, especially not in a low-level language like C.

Speaking of which, why are you focused on C? Do you have a particular reason for this choice of language?  C is a "low-level" language, which means it works quite closely to how machines think, and quite differently from how people think. This is sort of like taking a math class that provides only axioms, and makes the student prove all of the important results on their own. I am not suggesting that there is no value there, but (1) it is much, much harder, and (2) you're more likely to simply give up in frustration when you can't seem to do anything at all, even after months of effort.

Beginners, particularly if self-taught, should start in higher-level languages where they can begin to learn how to actually undergo the process of programming without having to worry yet about pointer arithmetic and memory management.
