classSolution {public:intmissingNumber(vector<int>&nums) {intn =nums.size();intsum1 = n * (n +1) /2;intsum2 = accumulate(nums.begin(), nums.end(),0);returnsum1 -sum2; } }; 解法4:结合题目Single Number可以想到基于位操作的解法:将输入数组与[0,n]异或,最后得到的值即是缺失的那个。
Finding the missing side or angle couldn't be easier than with our great tool – right triangle side and angle calculator. Choose two given values, type them into the calculator, and the calculator will determine the remaining unknowns in a blink of an eye! If you are wondering how to fi...

A triangle is a three-sided polygon. Instructors often ask intermediate and advanced-level math students to calculate the missing angle in a triangle. One method of finding a missing angle is based on the premise that the sum of the interior angles of a
Calculator– I take for granted how easy it is to outsource the grunt work of basic math. I highly recommend using one that is allowed on the SE exam. I switched from a graphing calculator to the TI-30X IIS a year before I took the SE, fully expecting to switch back. I never did...

Requirements on the number of recon- structed b-jets (Nb-jets) are applied to ensure that the RRs are orthogonal to all analysis signal regions, which include a Nb-jets ≥ 3 requirement. Simulated events for these processes are first normalised to the total number of observed events in the...
