Nettet17. jan. 2024 · Each time a value occurs in the original array, you increment the counter at that index. At the end, run through your counting array, printing the value of each non-zero valued index that number of times. Example arr= [1,1,3,2,1] All of the values are in the range [0…3], so create an array of zeros,result = [0,0,0,0] . Nettet18. nov. 2024 · From the table above, there will be 28 set bits in total from 1 to 14. We will be considering 2 0 as A, 2 1 as B, 2 2 as C and 2 3 as D First of all we will add 1 to number N, So now our N = 14 + 1 = 15. ^ represents raise to the power ,not XOR. eg. 2^3 means 2 raise to 3. Calculation for A (2 0 = 1) 15/2 = 7 Number of set bits in A = 7 ————> (i) Nettet13. apr. 2024 · नमस्कार दोस्तों आप सभी लोगों का यूट्यूब चैनल पर स्वागत है आप सभी के लिए ... playground icon vector
