number.Case #2: 4 is an Unhappy number.Case #3: 13 is a Happy number.
Question:The so-called Happy number is to give a positive number s, then calculate the sum of squares on each bit of it, get its next number, then the next number continues and select the sum of squares on each ...... If we continue to calculate and there is no previous Number but 1, congratulations, this is a Happy Number.If a previous occurrence occurs during the calculation process, it will not be Happy.

the hidden bit scheme ). Due to the variation of the form of the tail number, the order code is also different from the general shift code, for the short real number, [X] shift = 27 + X-1 = 127 + x, that is to say, this type of transfer code is 1 smaller than the general value of the transfer code, such. [810] shifted to 13310 instead of 13410. Therefore, the offset of the short real number, the long real number, and the temporary real number are 7FH

Each time the concatenation is done, the two pieces of rope are folded in half, and then set together as shown. The resulting rope is again treated as another piece of rope, and can be folded in half to another string. After each concatenation, the length of the original two-segment rope will be halved.

analysis, the highest DPI value for mdpi density is 160, and the maximum DPI value for xxhdpi density is 480, so it's a 3 times-fold relationship, so we can guess, Images placed under the drawable-mdpi folder will be magnified 3 times times on xxhdpi density devices. corresponding to Android_logo, the original pixel is 270*480, which should be 810*1440 pixels after zooming in 3 times times.

Let's try again and move the picture to the drawable-xxxhdpi directory. The maximum DPI value for the xxxhdpi density is 0.75 times times 640,480, so we can guess that the images placed in the drawable-xxxdpi folder will be reduced to 0.75 times times the size of the xxhdpi density device. 270*480 0.75 times times should
