Binary floating point math is like this. In most programming languages, it is based on the IEEE 754 standard. The crux of the problem is that numbers are represented in this format as a whole number times a power of two; rational numbers (such as 0.1, which is 1/10) whose denominator is not a power … Read more
in the actual code there is a differentiation between old interval ranges and new ranges after applying certain operation those ranges would be merged together. I wanted to split the question into smaller chunk so the merging part is left out. Solely: It is easier to merge in the new interval directly, instead of artificially … Read more
An algorithm to list the elements from innermost to outermost is to pull off the last and first entries (pop and shift) in the array in alternation until no elements are left, then reverse the list of what you have pulled off. This works for odd and even-length arrays naturally. For example, 1,2,3,4,5,6 1,2,3,4,5 6 … Read more
You basically half-answered the question yourself: It makes sense to use a stack, since you can push and pop to/from a stack in the same order as the compiler would do it too, if you used recursion. Doing things the way people expect them to happen is a good thing (even if you can do … Read more
Let fabs be a function that returns the absolute value of a float. Then the formula could look like this: function calcRank(float v1, float v2) { float k = fabs(v2-30.0); if (k < 30.0) { // Rule 1 and 2 rank = k/60.0 + (60.0-k) * v1 / 60.0; } else { // Rule 3 … Read more
Yes on all four. To clarify, the term “pair” in UTF-16 refers to two UTF-16 code units, the first in the range D800-DBFF, the second in DC00-DFFF. A code unit is 16-bits (2 bytes), typically written as an unsigned integer in hexadecimal (0x000A). The order of the bytes (0x00 0x0A or 0x0A 0x00) is specified … Read more
I don’t recommend you to use break statement if it’s not strict necesary it’s use. It isn’t a good practise in programming (look at this: Is it a bad practice to use break in a for loop?) and I recommend you to use another alternatives, instead of break that could make the same work. For … Read more
The stack is the memory set aside as scratch space for a thread of execution. When a function is called, a block is reserved on the top of the stack for local variables and some bookkeeping data. When that function returns, the block becomes unused and can be used the next time a function is … Read more
