A number chain is created by continuously adding the square of the digits in a number to form a new number until it have be En seen before.For example,44→32→13→10→ 1 → 185→ →145→42→20→4→16→37→58→ Therefore any chain this arrives at 1 or the become stuck in an endless loop. What are most amazing are that every starting number would eventually arrive at 1 or 89.How many starting numbers below ten million would arrive at 89?For a number within 10000000, the sum of the squares of each

This article mainly introduces the implementation code of the php digital verification code, which has some reference value. if you need it, it is very convenient to refer to implementing the verification code in php, the key point is to master the usage of the php gd library and session. Looking at the Online php verification code generation example, there is no combination of php gd library and session, and php is used to generate a random number. PHP verification codes can be divided into ma

HDU 3555 Bomb [digit] DescriptionThe counter-terrorists found a time bomb in the dust. but this time the terrorists improve on the time bomb. the number sequence of the time bomb counts from 1 to N. if the current number sequence between des the sub-sequence "49", the power of the blast wocould add one point. Now the counter-terrorist knows the number N. They want to know the final points of the power. Can you help them? InputThe first line of input

The first line of the input was a single integer T which is the number of test cases. T test Cases follow.Each test case is contains a single positive integer N (1OutputFor each test case, you should output the rightmost

Neural Networks for Digit recognition with PybrainPosted on January. by powel talwar Hi EveryoneAs a part of my B.Tech project, we were required to make a neural network, among other things, which can train on given dat A and perform the task of Digit recognition. We chose Python to do with project in given the wide array of libraries.We aim to identify digits from images. The dataset is a part of MNIST da
