I was reading 2D BIT, gfg implementationhttps://www.geeksforgeeks.org/two-dimensional-binary-indexed-tree-or-fenwick-tree/ Please help me with some doubts, In the updateBit and getSum function inner "y" loop is not initialized again. Is it a mistake or is it meant to be that way?

The paper show that the Binary Indexed Tree has the following advantages: Is faster than other data structures that allow the same types of operations. Can be adapted for a large number of distinct operations: sum, minimum, maximum, greatest common divisor (gcd), greatest common factor (gcf)...
Binary Indexed Tree的思想是,每一个整数都可以由几个二进制指数的相加和唯一表示: 例如:11 = 2^3 + 2^1 + 2^0 这是因为每个数的二进制表示都是唯一的: 11 的二进制表示1011即对应了上面的式子. Binary Indexed Tree 要处理的这个数,就是下标。 按照Binary Indexed Tree的逻辑, 我们要计算下标1~11的元...
