You are standing at position 0 on an infinite number line. There is a goal at position target. On each move, you can either go left or right. During the n-th move (starting from 1), you take n steps. Return the minimum number of steps required to rea…
A move consists of taking a point (x, y) and transforming it to either (x, x+y) or (x+y, y). Given a starting point (sx, sy) and a target point (tx, ty), return True if and only if a sequence of moves exists to transform the point (sx, sy) to (tx, ty…

前两天面试遇到的一个题,当时没有想清楚,今天想了一下,po出来: # -*-encoding:utf-8-*- import sys end = 0 # 终点 cnt = 0 # 统计组合方式 def jump(start): global cnt for i in [1,2]: cur = str(start)+"+"+str(i) if eval(cur) >= end: print cur cnt += 1 continue jump(cur) def main(n): &…
