Modular Arithmetic "mod" is known as the operator of Modular Arithmetic Given (a)mod(b)=c where a,b,c are integers(±z). Where a is the dividend, b is the divisor, and c is the remainder. #sharingisthenewlearning #mod #modulararithmetic
🔢 LeetCode Daily: Smallest Missing Integer ✅ Modular arithmetic magic! Track remainder frequencies, consume greedily from 0 upward. ⚡ O(n) with mod tracking 🎯 Remainder classes = equivalence 💡 Handle negatives: ((n%v)+v)%v #LeetCode #CPlusPlus #ModularArithmetic
#POTD #Math #ModularArithmetic #Tougher Problem of the Day! Here's a weird one today. Clearly we would never say that 7 = i. However, did you know that 7 is congruent to i, mod 10? That is: 7 ≡₁₀ i. Nice!
#POTD #Math #ModularArithmetic Problem of the Weekend! Here's the last in the series this week. You'll need to put on your thinking caps for at least one part, if not two. There are also (at least) two good ways to attack this one. Have fun!
#POTD #Math #ModularArithmetic Problem of the Day! We've been building up to tomorrow's Problem of the Weekend, and today's should be a piece of cake if you were able to make it through yesterday's finding of n's congruent to 𝒊. (I've been looking for the best i: 𝒊? ⅈ? 𝖎?)
#POTD #Math #ModularArithmetic Problem of the Day! Here's the followup modular arithmetic problem to yesterday's. If you're not already familiar with these, it's time to get your learn on! Extra Hint: there are more than two answers!

Tip: Keep on writing the definitions of notation you haven't internalised yet. Once those definitions have been internalised, do the same for new / more advanced notation. Keep going. At the end of the day, maths is a language as well. #modulararithmetic #maths
