1)RMS英文缩写为rootmeansquare翻成中文即为均方根,就是一组统计数据的平方的平均值的平方根。统计学计算公式: 12+ 22+ 32+⋯+ 2 22)有效值:在电气上周期信号的瞬时值随时间不断的变化,在测量和计算中很不方便,因此在工程中常常用有效值来度量周期信号的大小。周期信号的有效值是根据其本身的热效应与一...

For a 32-bit integer square root suitable for processors with no FPU or slow double-precision support, see this answer of mine. The square root of a 64-bit unsigned integer can be computed efficiently by first computing the reciprocal square root, 1/√x or rsqrt(x), using a low-accuracy...
Where sqrt(a) is the square root of a, and floor(b) is the integer value of b after removing everything on the right of the decimal point. There can be Q≤20000 queries. If we didn't have type 3 query, then we are left with standard lazy segment tree problem. How to handle 3rd...
