WebDec 14, 2024 · First Repeating Element Try It! Naive Approach: Below is the idea to solve the problem Run two nested loops, the outer loop picks an element one by one, and the inner loop checks whether the element is repeated or not. Once a repeating element is found, break the loops and print the element.
