WebbTbh, it's not worth using bits/stdc++.h.If you type out only the headers you need (with an autocomplete for standard headers maybe), you'll lose some seconds, but on the other hand, you'll save seconds of compilation time because the compiler won't have to go through all the headers on your system and figure out which declarations you need and … The short-time Fourier transform (STFT), is a Fourier-related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. In practice, the procedure for computing STFTs is to divide a longer time signal into shorter segments of equal length and then compute the Fourier transform separately on each shorter segment. This revea… WebbA fast Battle Speed (low B-MOD) reduces Charge Time while the Action Time stays the same. This means that setting the Battle Speed fast reduces the relative disadvantage of actions with long CTs, as the action stage stays the same. shaq playhouse

Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow t… shaq playing a genie
