💡 Analysis & Explanation

Requirement Breakdown ▼

We need to locate a highly specific sequence within the string: [Number] -> [Target Symbol] -> [Symbol]. The focus is entirely on counting the 'Target Symbol' in the middle.

Scanning the Series ▼

Methodically checking from the left side, we encounter the sequence '7 & &'. Here, the first '&' fits the criteria perfectly (preceded by the number 7, followed by the symbol &).

Finding the Next Match ▼

Moving further down the line, past the numbers, we spot another sequence near the end: '7 € €'. The first '€' acts as our second valid target.

Conclusion ▼

Scanning the entire string confirms there are exactly 2 symbols satisfying these exact positional constraints.
