The reason is, not all programming languages execute at same speed. For example, C is around 5 times faster than Java in most cases. Also, there are some cases, like in previous month's CodeChef long challenge, where people used PyPy to solve problems using brute force because it was unnecessarily given advantage of higher time limit. But, in most cases you'll not find any difference in the algorithms used to solve that problem in all languages as their time limits are carefully set. read less

What is meant by "bit masking"?
For example if you want to know if third bit is 1 or not for an int x then you can mask all other bits and just check the third one: (n & 0x04) != 0 means 3rd bit is not zero, 0x04 is the bit mask
