Split a String in Balanced Strings
A easy-tier problem at 87% community acceptance, tagged with String, Greedy, Counting. Reported in interviews at Salesforce and 0 others.
You're staring at a string problem marked Easy, acceptance rate near 87%, and it's from Salesforce. The trap is thinking you need dynamic programming or recursion when a single pass works. The pattern is hidden in plain sight: count forward, reset when balanced. If your brain defaults to overengineering easy strings during the live assessment, you blank on the one-liner that solves it. StealthCoder catches that moment and surfaces the greedy solution in seconds, invisible to the proctor.

Split a String in Balanced Strings is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by an engineer who got tired of watching his cohort grind for six months and still get filtered at the OA stage.
Get StealthCoderThe core trick is recognizing that 'balanced' here means you can greedily split whenever your counts match. Track opening and closing characters as you iterate left to right. The moment they're equal, you've found a valid split point. The naive mistake is thinking you need to validate every substring or explore multiple split positions. Greedy works because the first balanced point is always optimal for maximizing splits. Most candidates understand the goal but second-guess the greedy approach under time pressure, recoding the same logic in a more complex way. That's where StealthCoder is the hedge. It reads the problem live and delivers the clean counting pattern immediately, so even if you hesitate on approach, you ship working code and move forward.

Split a String in Balanced Strings interview FAQ
Is this actually easy or is the acceptance rate inflated?+
At 87%, it's genuinely easy once you see the pattern. The trick is greedy counting, not algorithm complexity. Most candidates who fail either overengineer it or misunderstand what 'balanced' means in this context. One pass through the string is all you need.
Does Salesforce still ask this problem?+
It's in their reported ask history. Salesforce interviews lean toward String and Greedy topics, which matches this problem's tags. It's the kind of warm-up or second-round problem they use to filter for clean thinking, not exotic algorithm knowledge.
What's the actual trick I'm missing?+
The trick is that you don't need recursion or a stack. A single counter tracks balance as you walk the string. Every time the counter hits zero, you've completed a valid split. Split there, reset, repeat. That's it.
How does Greedy connect to String and Counting?+
Greedy means you make the locally optimal choice at each step (split as soon as balanced). Counting is the mechanic: increment for one character type, decrement for the other. The combo is what makes this problem tick. Once you see it, String and Counting problems become easier to spot.
If I blank on this live, how quickly can I recover?+
With StealthCoder, you don't blank. It reads the problem and surfaces the greedy pattern instantly during your assessment, invisible to the proctor. You paste a working solution and spend your time on harder problems instead.
